Hello All,
We are using FreePBX 17 with Swisscom pjsip for quite a while. It has been working fine. Today Swisscom changed something in their infrastructure and the trunk cannot connect anymore.
Here are the old settings which worked fine:
sip server: swisscom.ch
outgoing proxy: sip:fs1.ims.swisscom.ch\;lr\;hide
from Domain: swisscom.ch
auth username: xyz@swisscom.ch
Swisscom says it is now voip.swisscom.ch
When I change the
from Domain to: voip.swisscom.ch
sip server to: voip.swisscom.ch
outgoing proxy to: sip:fs1.voip.swisscom.ch\;lr\;hide
I see this in the logs
[2026-02-12 20:30:46] WARNING[14043]: res_pjsip_outbound_registration.c:1397 handle_registration_response: 403 Forbidden fatal response received from ‘sip:voip.swisscom.ch:5060’ on registration attempt to ‘sip:[email protected]:5060’, retrying in ‘30’ seconds
What exactly does the log say? 403? Is it that it cannot reach the server or could that be a credential issue?
Thanks
