Hi,
I've the following setup that experience caller ID issue:
Cisco IP Phone --> CUCM (7.1.5) --> Cisco H.323 Voice Gateway (15.1.3.T) --- QSIG ---- Ericsson PABX --> Analogue Phone
1. Caller ID is ABLE to display when Analogue Phone make a call to Cisco IP Phone
2. Caller ID is NOT ABLE to display when Cisco IP Phone is calling Analogue Phone
I've got the "Display IE delivery" checked in the Voice Gateway settings @ CUCM yet caller ID is still not being displayed in Analogue Phone
Any advice on either CUCM / Voice Gateway / Ericsson PABX would be greatly appreaciated.
Thanks
