Outbound Caller ID

[smith13045]

Hello,

I am having issues figuring out how to make my outbound caller ID show the proper DID. We have multiple DID's on the system but it shows the default caller ID even thou I have set the DID in the Outbound caller ID in the extension settings.

Is this something that maybe is coming from my SIP Trunk Provider?

Or am I just missing a setting somewhere?

There is an outbound caller id setting on the trunk outbound trunk in 3CX however to see where the modification is taking place you would be best to PCAP from the PBX and see if it is sending what you want.

You maybe able to check the trace for P-asserted identity also.

It may be coming from the provider - some do not allow Caller ID overwrite.
If they do support it, ask them what SIP field they expect to see it in.

Who is the provider? Others may have experience with them, and the setting required to make it work, If they allow it.
