Calling in to Intercom System

[csr]

Does anyone have experience hooking up a Fortivoice system to an Rauland TCU intercom system? At all of our other locations our users are able to any phone by dialing an extension number to call in to the intercom system then on to the zone. We only have one site that has a Rauland system and can not get it to work. We just get a busy signal.

To all SE, I'm on it, It seems to be just a misconfiguration issue, will update the result on this post once resolved.
