In individually created provisioning files, this change must be transferred manually.
<subscriptionFailureHandling>...</subscriptionFailureHandling>

Transfer configuration

A configuration can now be transferred from one variant to a specific other variant.

Bug Fixes

Analogue fax machine

With some providers it was not possible to send fax messages in the local phone network.

Note: : If an analogue telephone and a user instead of an external device fax were temporarily configured as a workaround, this must be reversed.

Logging into the Web Interface

Only applies to version 2.2.0 COMtrexx Next: After deleting all contacts, it was no longer possible to log in.

LDAP

If automatic exchange line request was switched off, the 0 for exchange line request was not transferred to the contacts. External calls initiated via the contacts failed. LDAP now checks the automatic exchange line request when a call number is requested. If the telephone number to be supplied has more than 4 digits, it is regarded as external and preceded by an exchange line access number.

Note: For the few exceptions where telephone numbers with less than 5 digits are external, these must be entered with the local area code.

If automatic exchange line request was switched off, no internal phone numbers/contacts were displayed for newly created users.

An unnecessary empty contact Admin was displayed in the COMfortel D-series phone.

LDAP / Voicemail App

If automatic exchange line request was switched off, the callback via the voicemail app did not work on a COMfortel D-series phone.

NAT traversal

The public IP address was also sent in the header, even if the option was switched off.

Presence

After logging out (roaming user), a COMfortel D-series phone was still displayed as available.

Call forwarding

External call forwarding was always carried out via accounts at the system location and sometimes failed. The account associated with the redirected number is now used.

Bug Fixes

COMfortel SoftPhone

Changing ports were used to connect to the proxy server. Now a fixed port is always used.

Softphones with a '+' in the password could not register. This remains the case. Automatically generated passwords no longer contain a '+'. For manually entered passwords, the '+' must be avoided/removed.

Note: When using the COMfortel SoftPhone for Windows, the IPv6 address of the PC must currently be/remain disabled for a stable telephony function.

Remote Backup

With larger amounts of data (e.g. due to longer announcements), error messages occurred during the backup.

Do not disturb status display

The status of the Do Not Disturb function was displayed incorrectly if the status was changed during a set rework time.

System messages

In rare cases, there were erroneous system messages regarding the fan.

Web interface

Codecs

The Codec G.729 could not be used from internal telephones.

D1-Net

Incoming calls from the D1 net were no longer signalled.

Fax printer driver

Communication between fax printer driver and COMtrexx was not possible. This is fixed with this version in conjunction with version 1.4.4.3 of the fax printer driver.

Note: If the use of HTTPS was temporarily switched off as a workaround, this must be reversed. This must be done on each PC used in the dialogue of the fax printer driver and here in the COMtrexx: Administration > Network > Server service > Force HTTPS connection

Import Provider template

After changing certain settings and exporting, provider templates could no longer be imported under certain circumstances.

Ringing sequence

The ringing sequence linear - fixed - rotating - split group did not work correctly.

Number presentation

Voicemail App COMfortel D series

When the voicemail app first accessed the COMtrexx, the voicemail boxes and messages were not displayed correctly.

In connection with the access of the voicemail app, problems could occur when accessing the web interface of the COMtrexx.

Voicemailbox: Save short messages

When this option was switched on, sibilant sounds were saved as a message after the caller hung up early.

Web interface

Administration > Maintenance > Message Configuration > Logo: A previously selected logo was no longer displayed when the page was called up again.

Administration > Network > Ports: The ports of the Auerswald Proxy was not displayed in the port view.
