This FAQ describes the simple first setup of Auerswald VoIP systemphones by using zero-touch configuration thus setting the phone's provider and account configuration by the PBX (basic provisioning).

Supported by the following PBXs (from version 6.6D):

• COMpact 4000
• COMpact 5000/5000R
• COMmander 6000/6000R(X)

Supported by the following IP systemphones (from version 2.6B):

• COMfortel 1400IP
• COMfortel 2600IP
• COMfortel 3600IP

Technical requirements:

• Active DHCP server on the network
• Phones are integrated into the network (e.g. by PoE Switch)
• Phones are in factory default settings
• Phones network-settings have been assigned by DHCP

Screenshot of the phone's Zero-Touch-configuration (only displayed in factory default):

Procedure:

1. Create a VoIP-subscriber
2. Grant access authorisation to the provisioning file (standard.xml) for the subscriber:

Note:

The Phone language can be set in the pbx:

Due to the increased volume of telephone traffic, the transfer points of VoIP providers may reach their capacity limits. A solution is sought by the providers through load balancing. The load distribution is done with a DNS SRV query. The DNS SRV is used to enable the provider to notify the registrars prioritised by him. The DNS resolution must be carried out by the provider. For this purpose, the router must use the DNS servers of the provider.

Current ICT systems:

• COMpact 4000
• COMpact 5000 (R)
• COMpact 5200 (R)
• COMpact 5500R
• COMmander 6000 (R) (RX)

Note the following points in the configuration:

• Under public networks, VoIP, provider, configure the appropriate provider. The default value 5060 must be set as registrar port and for the outbound proxy. The current templates are already preset for this.
• Under Administration, IP Configuration, the IP of the router or gateway must be entered in the 1st DNS Server field.

Early generations of hybrid telephone systems:

• COMpact 3000 analogue, ISDN and VoIP
• COMpact 5010/5020 VoIP
• COMmander Basic.2 / Basic.2 19“
• COMmander Business / Business 19“

These systems do not support the dynamic procedure and can therefore no longer be operated on the respective VoIP account after platform changeover. In these cases, the ICT system must be replaced by a compatible system.

Aaron

Aaron.ai is listed as a VoIP Provider, but Aaron is actually a service provider that offers automated Voice services, as such no calls can be placed or received through a Aaron trunk. Aaron provides their customers with a dedicated number for their SIP services which allows the customers to forward calls to this number (and this number only) on a Aaron trunk.
To make sure that only the dedicated calls a routed to Aaron and no other calls are routed this way some special settings are required.
Step 1: under “Public switched tel. Networks”→ VoIP→ Provider click import and select the Aaron template.
Step 2: under VoIP→ Accounts add a new Account with the credentials provided by Aaron.
Step 3: In “Subscriber (scr.)”→ Profiles → Configuration add a new profile named “No Aaron” based on “Standard Phone”, which has to be assigned to all telephones with outside lines instead of the “Standard Phone” profile. Activate the Profile override for “Exchange line authorisation” and switch it to “Exchange line dependent”. Under “Expert” switch Aaron to “Only internal” and save the settings.
Step 4: Assign the new profile “No Aaron” to all phones.
Step 5: Add a new Dummy Subscriber which will be used to forward calls to Aaron. The Dummy can not use the Profile “No Aaron” but will have to use the Standard phone profile. However in “Subscriber (scr.)”→ Phone numbers → (Dummy Account) → “Exchange line settings”→ “Exchange line authorisation” you have to switch it to “Exchange line dependent” and use the Expert button to set all providers beside Aaron to “Only incomming”. Aaron should be switched to National or International if the number Aaron provided you is not a national number for you.
Further you will have to set and activate “CF (call forwarding) immediately” to the SIP Access number provided by Aaron and activate “cascading” for the Dummy Subscriber.
Save the settings.

Take note: If further subscribers are added you have to make sure they use the “No Aaron” profile.

Use: by setting CF on busy or CF on no reply to the number of the dummy subscriber, calls can now be transferred to Aaron.

Hackers always use the same method: they are looking for companies whose PBX has an integrated voicemail function (answering machine) in order to manipulate it via remote access. All PBXs that have been recently manipulated showed poor security measures such as insecure PINs. Auerswald PBXs have sufficient security mechanisms. But they have to be used!

Therefore, please follow the following recommendations to protect your Auerswald PBX against such attacks:

1. The admin PIN, the user PIN or the voice mailbox PIN can be used for the remote access. Do not make it easy for the attacker and use complex PINs (The PINs in the PBXs consist of six digits. Number sequences such as "123456" or "111111" or birthdays are NOT secure. It makes more sense to use random number sequences.
2. If possible, use the blocking functions for incoming calls (e.g. block calls from abroad).
3. It is more secure to use message forwarding via email and to disable the remote access.
4. For outgoing calls, prefixes (010…) in order to make the call cheaper are often used so that the protections of the Telekom (detection of high costs in a short time) are not effective. You can secure your PBX by using the blocking functions for outgoing calls (e.g. for calls that begin with 010).

Important information about "Emergency calls"

As installer and operator (customer) of telecommunication equipment you are legally obligated (Telekommunikations­gesetz § 108) to ensure the unhindered and prioritized routing of emergency calls (numbers 110 and 112).

Therefore please note the following essentials:

1. In order to be able to make emergency calls without any special knowledge at any time, the PBX's emergency numbersmust not be deleted. Otherwise the number is called wrong or is not possible at all!
2. Furthermore the funcion "emergency call has priority" must stay enabled.
3. From firmware version 6.6B on it is no longer possible to delete the statutory emergency numbers on the Auerswald PBXs COMpact 4000/5000 and COMmander 6000/6000R/6000RX. To use internal numbers beginning with 11... the optional setting to only call emergency numbers with exchange line access number can be enabled. If this special setting is enabled instruct every user of the PBX on how to dial emergency numbers and also label the phone accordingly to not violate § 108 Telekommunikationsgesetz
4. Also check whether the number 116117 (emergency medical services) is already configured. On new installations this number must be configured as a service number. On older systems, where there are no service numbers, configure this number as emergency number also.

Note: Update your COMpact 4000/5000/5000R or COMmander 6000/R/RX to the current firmware as soon as possible and on older systems check the configured emergency numbers 110 and 112 as well as the emergency medical services 116117.

Since the annoucement before answering is only configurable for groups, the waiting field has to configured for a group. If the waiting field is configured for a single subscriber, an announcement before answering can't be configured.

Storage specifications (USB stick, SD-card)

USB-stick

SD-card

Info for using 16GB SD-cards:

Please note that the device's operating speed can get reduced due to the larger storage size.

In this case it is recommend to format the SD-card to 4GB with a PC.

In order to select several subscribers in the PBX's call-distribution settings, a group has to be generated with the respective subscribers as members. The group can then be selected in the call-distribution settings.

The transmission path from the system to the mail server / mail provider is usually encrypted using SSL/TLS.
Encryption of mail and attachments up to the recipient of the mail (end-to-end encryption) is not possible.

Only for external VoIP accounts or on an analogue terminal. On external ISDN connections, to ISDN or VoIP extensions, caller identification cannot be prevented.
In the configuration of the VoIP provider used, a user-defined evaluation can be defined under Evaluation of incoming SIP messages, in which all selections for search prioritization are set to None.
For analog terminals, the CLIP info can be deactivated under Subscriber / Function overview / Analogue settings.

Yes, the recording of incoming and outgoing calls can be deactivated in the COMpact 4000/5000/5200/5500 and COMmander 6000 PBXs under User data / Call data / Settings.

Preparations

Preparing the PBX for Remote Access

• Activate "Enable dealer access via internet" in "Settings -> Remote Configuration" on the PBX.
• If using method 2 you also have to define a remote switching number as well as an external PIN.

Registering the PBX in ARA

• Go to "Registrierte TK-Anlagen" (registered PBXs)
• Press the "+"-symbol to register a new PBX.
• Enter at least the serial number, a name and the type of PBX of which you want to access.

Activating remote access

Method 1: Activation by any internal phone

• Tell your customer to dial the following sequence on any internal phone:  ##8 Admin-PIN | Subadmin-PIN | Benutzer-PIN * 91 # (example: ##8 471208* 91 #)
• Click the refresh- (next to the "+"-symbol) and then the "Verbinden" (connect)-button in ARA.

Method 2: Activation by the dealer from a distance

• Dial the previously configured remote switching number from any external phone.
• After the switching tone enter the following sequence: ##8 external PIN * 91 # (example: ##8 471108* 91 #)
• Click the refresh- (next to the "+"-symbol) and then the "Verbinden" (connect)-button in ARA.

A static IP address of http://192.168.1.111 is preset in the delivery state. The access data:
User name: admin
Password: admin
The current IP address can be queried on an ISDN telephone using the code ##8*941#.

The IP address is only displayed on the directly connected ISDN telephone, not on the internal S0 bus of our telephone systems.
Info: Display messages are used
COMmander Business and COMmander Basic.2 only: A replacement option is the automatic callback from the VoIP/ISDN gateway. With this callback, the IP address is then transmitted as the phone number.

Until the maximum number of call data records is exceeded or the entries are manually deleted from the call data list.
If the maximum number of call data records is exceeded, the oldest entries are overwritten.
It is not possible to define a time period after which the call data is automatically deleted.

No, all messages are stored on the storage medium (USB stick or SD card) unencrypted. The storage media of COMpact 4000/5000/5200/5500 and COMmander 6000 have the ext4 format and are therefore usually not readable on a Windows PC without additional software.
The storage media of the system telephones are in FAT/FAT32 format and can be read out on a Windows PC without additional software.

Under the following conditions the PBX can signal the busy-tone for addional incoming callers:

1. The external call is distributed to only one subscriber; call-waiting must be disabled. Also no parallel call or call-forwarding on busy must be enabled for the internal or external number.
2. Busy-on-busy is enabled for the external or internal group-number (depending on the PBX). In current systems the maximum number of connections before the busy-tone is played back can be set.

 If these conditions are met, additional incoming callers get the busy-tone. If it doesn't work it is not the PBX's fault anymore. What could be the cause now?

1. The PBX is not operating directly on the public line and might be connected to the internal ISDN-port of a VoIP-router for example. In this case the PBX is signaling busy to the router. The router on the other hand only recognizes a busy device and eventually calls other devices (depending on the router's own call-distribution). Here it should be checked whether the router also provides a suitable setting or if the PBX can be connected directly to the public line without router.
2. Another possibility is that another device is operating in parallel to the PBX (e.g. an alarm-system). Here the PBX signals busy to the provider but the other device is available for incoming calls and therefore rings; the caller gets the ringing-tone, not busy. In this case it should be checked if it is possible to disconnect the parallel device from the public line and connect it as internal subscriber to the PBX or the device must be set to not react to incoming calls. For further information the manufacturer of the device should be contacted.

How can I verify that the PBX is correctly signaling busy?

The PBX's call-distribution should be set to signal more than one subscriber, busy-on-busy is enabled or set to "from 1st connection on" (depending on the PBX). For the first incoming call all the configured subscribers ring and one of them takes the call. For the second incoming call no additional subscribers should ring. If they do the PBX's configuration should be checked. If the caller gets a ring-tone but the PBX's subscribers don't ring, one of the above described examples applies. If the caller gets the busy-tone, the function is ok.

Requirements:

• Auerswald COMpact 4000, COMpact 5000/5000R, COMpact 5200/5200R, COMpact 5500R, COMpact 5010/5020 VoIP or COMmander 6000/6000R/6000RX
• LAN-TAPI-driver from version 2.4.0.6 and up installed

Configuration:

If not already done so, enter your dialing rules and location information in the telephone-/modem options (Windows Control Panel). Enter the connection information (IP-address, port, LAN-TAPI-password) in the LAN-TAPI-driver's settings.

On the PBX's menu check or otherwise change the LAN-TAPI-settings (IP-address, port, LAN-TAPI-password) according to the driver's settings.

Make sure that any necessary dongle licenses were purchased and also create a list of LAN-TAPI subscribers in the PBX's LAN-TAPI-settings.

Deactivate the RAS-service in your server's admintrative tools and reboot the machine. After the reboot restart the server's telephony service.

Test:

Run the Windows dialer and set the subscriber you want to test in the options.

Enter a destination number and dial.

Network and computers

• Maintain a stable network environment. The TAPI-server needs to have a permanent connection to the PBX.
• Remove any unnecessary TAPI-related entries (e.g. HID, 323 etc.) in the advanced Telephone-/Modem options (Windows Control Panel).
• Check if the operating system of the participating computers is supported by our driver or software.
• Operation of LAN-Tapi services on several clients is possible if a domain controller (DC) with configured telephone service is available and the clients connect to this DC.
• Operation of LAN-Tapi services on a single client is possible if the driver is installed on this client.
• Please ensure that the LAN-Tapi-driver is only installed once across the network.
• On a terminal server it is not possible to control access rights to subscriber lines. For this reason this type of installation is not recommended.

PBX

• Check whether the PBX supports LAN-Tapi. For information see the features summary for the PBX on www.auerswald.de.
• By default our PBXs come with a certain number of LAN-tapi lines that can be used. Additional lines can be purchased in the Auerswald online shop shop.auerswald.de.

Telephones

Depending on the phone the full extent of the LAN-Tapi functions may not be available. For example, among others, automatic call setup, toggling and forwarding calls is not supported with standard phones (non systemphones). For more detailed information please see the description of the LAN-Tapi driver on www.auerswald.de.

Software

• CTI software usually requires separate paid licenses from the manufacturer. These licenses must be purchased in addition to the licenses for the PBX's LAN-Tapi lines.
• With PBX-Call Assist the purchase of the software licenses is necessary from the first subscriber (the LAN-TAPI activation for the PBX is already included in the same number).
• When using PBX Call Assist in a terminal server environment, please note that the PBX Call Assist client can only be used without TAPI or with standard TAPI (outgoing dialling only). Using the extended remote TAPI driver (outgoing dialing and display of incoming calls) in such an environment is not possible (will be queried during the installation of the client software).

PBXs with external ISDN connection

If you have a router that supports IP-telephony which also offers an internal ISDN-port (S0-port) you can generally connect the PBX's external ISDN-port to it. It is to note however that the PBX is now operated as a sub-PBX behind your router. Various features which are controlled by the network provider and operated by the PBX (such as call-forwarding via provider) can no longer be used. Since this is also dependent on the router we can't provide a listing of what exact features these are.

PBXs with external analog connection

If you have a router that supports IP-telephony which also offers internal analog ports you can generally connect the PBX's external analog port to it. It is to note however that the PBX is now operated as a sub-PBX behind your router. Various festure which are controlled by the network provider and operated by the PBX (such as call-forwarding via provider) can no longer be used. Since this is also dependent on the router we can't provide a listing of what exact features these are.

PBXs with external VoIP connection

If your network provider also provides you the necessary data (e.g. username, password) and allows operating alternate hardware, the VoIP-accounts can be configured directly in your PBX. A converter/gateway (e.g. VoIP-to-ISDN gateways) is not necessary. For this the PBX just has to be integrated in your network, so it can access the internet.

Note: These settings apply to all Auerswald PBXs that provide external internet telephony (VoIP).

COMpact 3000:

In "configuration -> Voice over IP (VoIP) -> VoIP provider" enter a name for the new account, select the according VoIP provider as well as the connection type and click on the green plus-symbol to generate the account.
