Getting error "Signaling Resources Unavailable"


I doing an outbound call to an IP but I’m getting this error
(Got SIP response 503 “Service Unavailable(Signaling Resources Unavailable)”)

the outbound context in the sip.conf


any help?

The SIP response came from the remote side. You’d need to investigate or inquire with the remote side as to why they would send it, such as your configuration being incorrect. Without that information it’s all just guessing.

A packet capture of the SIP request you sent, which got this reply, would be a
useful starting point.

Also, have you sucessfully placed a call to this peer in the past, or is this
something that you’re trying for the first time, and isn’t working?


it was working in the past and suddenly it stopped working.
