While it’s clear that outbound dialing with
siptrunk fails, it does work with a different provider,
telnyx, suggesting that there’s no networking problem preventing outbound calling:
I don’t know the significance, but I do see, on line 348:
<--- SIP read from UDP:220.127.116.11:5060 ---> SIP/2.0 404 Not Found
what does that indicate? Is that the root problem, or just a symptom?
What isn’t being found? The server at siptrunk?
