I’ve been running FreePBX on Raspberry Pi for a long time.
It had a few problems in the beginning due to ISP restrictions but they managed to work around it and was running for a year without issues.
A week ago, SIP trunk couldn’t register.
I’ve changed the password on ISP web portal and I can register again, however can’t make any calls.
As a test, I’ve installed Zoiper and configured the same account.
It works flawlessly. Also works on other equipment (Thomson router)
Problem is on FreePBX, when trying to make a call, I always get busy signal (outbound routes are fine, didn’t change anything).
I’ve tcpdumped logs from FreePBX and my local computer (with Zoiper). Also, added SIP log from the asterisk console if it helps. I can’t figure it out what is wrong. If there was any change, it’s on the operator side, the following config was working fine:
