DID not routing correctly

[Ricky Horne]

Hi,

I have all DID on 1 SIP trunk.
I have individual incoming routing setup so that the DID's go to the correct user extension.
All calls that go to any DID are routed to the main DID number set up in the SIP trunk

Sounds like you have set this up correctly however please double check using the below:

There are also several suggestions on these strings here:

Hello @Ricky Horne

If the calls are all routing to the main trunk number that means the PBX cannot match the called number to a DID of the system most probably because the format the provider is sending the number does not match the format you used to add the DIDs to the management console.
To avoid this you can either set up your DID's according to the format that arrives at the PBX or use a * to let the PBX know to match only the numbers after the *. So you can set the number of the previous example as *12345678 so it will match the number if the number arrives as 004412345678 or 4412345678 or 12345678. The * can only be used at the beginning of the number.

I am just waiting on my SIP provider as they are sending the SIP ID in the header rather than a telephone number.

Cheers for the help.

Glad we could assist. You could also use a supported provider to avoid compatibility problems and have all settings pre-configured in the template. https://www.3cx.com/partners/sip-trunks/
