SIPS-730 — Next-hop for request cannot be determined
The destination for a new session is determined by several ways:
the PLUG-TO configuration item
the original target in transparent case
a UA that has been previously registered.
The SIP proxy has received a request establishing a session but the destination is unknown. The reason can be one of following:
an incoming call that occurs after removing SIP YP map file prior particular UA registered
missing PLUG-TO directive or another ACL misconfiguration
an intrusion attempt.
The session is terminated.
