Caller ID Outbound

[servit.co.uk]

I manage a number of systems and one of my customers is moving from V11 hosted internally to V15.5 hosted externally.

Both systems have been set up to use the same SIP trunk - worked with the provider to allow this - but we have a problem.

On the V11 system we have set a specific outboud caller ID (One of our DDI's) which works fine and has done for years but on the V15.5 whatever and wherever I set the caller ID to I just get the default number of the trunk.

Any ideas please?

Hello @servit.co.uk

Check the outbound parameters of the 2 trunks and make sure they use the same settings. If they do then contact your provider and ask them why you are getting this difference. The should be able to tell you if a wrong SIP field is used or its an issue on their side
