I need to integrate CUCM 6.0 with Nortel CS1000M for my client. I put an MGCP gateway and configured QSIG trunk
beteween CUCM and PBX. The connectivity is like this
CUCM --> MGCP --> QSIG --> PBX
Now the calls are working both ways from IP Phones at CUCM to POTS phones at PBX and vice versa. Caller ID and
Caller Name are going from PBX to CUCM. But NOT from CUCM to PBX. The client is taking care of their PBX configuration,
they use QSIG variant (IFC:ESIGX ESGF) at PBX. I am using default QSIG configuration on CUCM. i.e. ISO QSIG E1.
I have already enabled the commmands " isdn outgoing ie facility" at the gateway. Below are the some commands enabled at the gateway.
no ip address
no logging event link-status
isdn switch-type primary-qsig
isdn timer T310 120000
isdn protocol-emulate network
isdn incoming-voice voice
isdn bind-l3 ccm-manager
isdn outgoing ie facility
isdn outgoing ie extended-facility
isdn outgoing display-ie
isdn outgoing ie connected-number
isdn outgoing ie caller-number
isdn outgoing ie caller-subaddr
isdn outgoing ie called-number
no cdp enable
Can anyone confirms the configuration and shed some light if my above configuration and signalling are compatible. I also see a QSIG variant ECMA in service perimeter at CUCM but dont know if its compatible.
I dont know anything about Nortel configuration. Is it possible that incoming CLID and Caller Name is not enabled at Nortel PBX for incoming calls.
Thanks in advance.
