Hi Somesh,
We are trying to implement ICMP error handling.Its clear from RFC
that ICMP error for request should be treated as 503 error response.
But the same is not clear for responses(both invite and non-invite
transaction responses).
It would be helpful if you can give any reference on handling of ICMP
error for sip messages.
Thanks and Regards,
Sunil
