CCM 4.1(3) Caller ID issues with a certain telco

Outgoing caller ID displays correctly except when calls are outgoing to Verizon Wireless cell phones. Now Verizon Wireless customers get unknown number. Previously Verizon wireless customers did get Caller ID info from my CCM system.

This issue manifested itself when the system was upgraded to 4.1(3). I have ben informed that this had been an issue at one time in the past but had been resolved. Unfortunately I am unable to contact the previous admin to discover how it was resolved. Previously the system was running CCM 4.0.

Re: CCM 4.1(3) Caller ID issues with a certain telco

The exact config needed will be dependant on the provider. The changes will be made in the Outbound Calls section of the GW config in CCMAdmin. Look for the following parameters:

Calling party IE number type unknown*

Calling Numbering Plan*

If they are set to unknown then that might be the problem. Changing them to the following might help:

Calling party IE number type unknown* -> National

Calling Numbering Plan* -> ISDN
