To connect a remote *ISDN* intercom to the CUCM, I have to use a 'ISDN to SIP' converter.
That saves me to get a BRI on that location.
Patton model: Smart Node SN-DTA/2BIS2V/EUI
Setup:
the Patton is connected to the CUCM as a SIP phone.
The Patton registeres itself correctly to the CUCM.
I know If I would use a trunk instead of a phone, I could use all ports, but that is not important. The intercom should work!
Problem:
When I press the intercom button, the call goes to the CUCM extention without problem. (altough it takes 4 seconds silence until the phone rings?)
When I pickup the reciever the line is busy directly.
When I call the intercom, it rings immidiately. But is also busy when answering.
According to Patton/ Patton debug log (looks like a cisco router;-)

After some digging: when I enabled "MTP (Media Termination Point)" in the phone properties (in CUCM), I was able to call the intercom.
Not that I am going to use it, but it's a step forward.
What can you suggest/ do to make a call with the intercom?
PS. I tried to setup a H.323 phone, but that option/that phone template is unavalable in (our) 7. Any sugestions to add that option?
