I connected cisco 3800 router with ericsson MD110 exchange using QSIG over E1 Pri. Calls are forwarding properly over ip network but few features are not being enabled specially CLI feature. I found a documnet where a command "caller-id enable" was issue in voice-port interface. But i go in this mode using command voice-port 1/0:15, no command caller-id find. My topology is below:
MD110 PBX ----3845---------3825----MD110 PBX
Waiting for immediate positive response.
you PBX is not sending calling number:
Calling Party Number i = 0x01A1, N/A
This can happen for example if the PBX was configured to be connected to PST and not send the calling number.
You need to have the PBX configured to send calling number. Unless this is done, router will never be able to display it.
