Twillio SIP

[mapham]

Hi

I have a 3cx that is hosted with LightSail and I used as one of the SIP providers Twillio Elastic SIP trunks
It seems like most of the things seem to be working just fine but here and there I get an error, with twillio
"32204 - SIP: 'From' phone number not verified "

Acording to them, when 3cx makes a call to that trunk, it showing as the request [email protected] ..
For twillio to work the request has to be the phone numbner

+########@3cx.pstn.twilio.com where the ### is the main number verified with twillio

I tried several changes in the from field but does not seem to work.
Any ideas ?
Tx

Have you followed - https://www.3cx.com/docs/twilio-elastic-sip-trunking/

Use the SIP template under Worldwide



I suggest deleting the sip trunk and starting again, using the info above

Hi Saqqara
Thank you .
I typed Twillio in the search before but got separate results.
The outbound rulles seem to be working is jus that twillio needs to receive in the request the twillio verified number and not the extension that calls.

Hi @mapham

Just make sure that all extensions making calls using the Twilio do not have different caller ID assigned to them under their extension settings.
To avoid that just add your Twilio main trunk number in the outbound rule next to the route with your trunk.
This overrides all other caller ID settings you might have.
Also put the outbound parameters back to their default values to avoid any issues.
