OfficeMaster Gate has two PCM interfaces for integration of 3rd party devices. One of them can be used for communication between SfB and 2N IP Intercom. We need to define both of directions of communication coming from/to ISDN interface in OfficeMaster Gate. The direction "Calls from ISDN" can be the outgoing connection to 3rd party platform such as SfB. "Calls to ISDN" is a part of configuration used for 2N IP Intercom.
