SIP trunk keeps disconnecting

[leyanu]

Hello Team, I am currently using unsupported trunks which has been working fine but for the last 3 days they keep disconnecting and refusing to reregister until I manually refresh registration. I am in Nigeria and I use version 18 with 1024 SC.

PS: I have used these trunks for weeks.

Hi @leyanu

Did something change on the PBX side like a firewall configuration or a new modem that would cause an issue? If not then I would recommend contacting your provider and asking them why are the trunks not registering.
Also what transport are you using? UDP or TCP?

Is your trunk problem following V18 install ? because V18 is not ready to use for production PBX, you should downgrade to v16
