Forward Call to Mobile has wrong Caller ID

[ssstofff]

We moved our sip trunk to a new provider.

Since then, when an external call is forwarded to the mobile number of an extension, the number of the caller becomes wrongly the Caller ID and the call is blocked by the provider cause wrong Caller ID.

How and what to update in orde the SIP Trunk Caller Id is used when the call is forwarded?

So it sounds like this was working before and then you changed SIP trunking providers and it's no longer working. Have you thought about asking your SIP trunk provider?

Compare the Outbound Parameters tab between the two trunks. Specifically check "From : User Part".

Ensure default caller id is configured under Caller ID tab of the trunk.

You may very well be attempting to send the caller ID of the originating caller. It may be that your new provider does not permit this. As suggested, you might want to check with them, before making any changes.

Thx ItcTech, that hint helped to resolve the problem.

In 3CX, I updated the "From; User Part" to 'OutboundLinedId' to force to set the SipTrunk number as caller when an internal forwards happens to an external number.
