Our setup is like this. IPC PBX has a Qsig E1 on VG which is connected to PSTN and CUCM. Unity 5.1 has SCCP integration with CUCM for ip phones and SIP integration for IPC phones VM. Incoming calls from PSTN easily transfers the call to VM for IPC phones on either busy or no answer.

Is it something wrong with the IPC PBX ? how it works for PSTN but does not work for Cisco phones ?
