Can I use a doorphone at a COMpact 3000 analog/ISDN/VoIP?

The COMpact 3000 analog/ISDN/VoIP PBXs don't feature an interface for FTZ-standard doorphones.

However, you can use analog doorphones such as our TFS-Dialog 20x/30x/universal plus. In addition, you can use the TSA - a / b use this converter can convert different doorphone to a / b port .
