Hi Guys,
I have inbound SIP provided by Gradwell in the UK. When I forward the relevant ports directly to a phone,with no setup, I can receive calls.
I would expect setting anonymous calls to Yes in Freepbx to work without issue but I’m having no luck.
I have an ANY-ANY > extension No. inbound route setup and I have tried temporarily disabling the firewall.
I have to use anonymous calls as my provider has a very long list of IPs
Any help much appreciated!!
Should be easy to solve if we see the logs including SIP logging. PJSIP or chan_sip?
Thanks for your reply,
I don’t suppose you have a link to a guide on pulling logs? Google isn’t proving very useful. All I can find is that I need to look in /var/log/asterisk/ but not how to get to that point.
Don’t use Anonymous SIP.
See the list of 14 netblocks at the bottom of
https://my.gradwell.com/s/article/what-ip-addresses-may-gradwell-send-voip-traffic-from
Type them, separated by commas, into the Match (Permit) field of your pjsip trunk.
Calls will no longer appear as anonymous.
Edit: here you go:
