Incorrect number showing on DID

[DJ Hattingh]

Good day,

We have a client that is making use of 3CX v20 and is experiencing the following issue.

They make use of a main SIP trunk and about 37 DID's. Each extension is linked to their own DID. They would like the extensions to show their corresponding number when dialing out. However when they call out it is only showing the main SIP trunks number

We have setup an extension as a test by completing the following:
- Setup the DID as a SIP trunk
- Removed the DID from the main SIP trunk
- Created an outbound rule for the extension to use when dialing out
- Ensured that this rule is above the other rules
- Added the SIP number to the External ID on the extension
- Made several changes to the Outbound rule to try and get the number to show correctly

Any suggestions on what I can do to resolve this will be assisted. I am willing to repeat any changes that I have made to test again.

Your assistance is appreciated.

The provider have clip no screening active? Is it an supported provider?

According to them they do have it active. The provider is shown as Supported (With limitations). I had a suspicion that this could be the problem but the SIP provider is adamant that it should work
