I am facing continuous issue with asterisk where asterisk stops responding to the incoming calls. The end user(Caller) get a busy tone in this case. On restarting asterisk the line starts working fine.
I am unable to detect when this happens and issue is generally raised by the client which is not obviously not right.
This issue could be due to the SIP line bouncing but i am not very sure of it.
Can we detect when the SIP line stops working? Also can we handle this automatically without manual intervention?
