You will get an ICMP if you're lucky. But if the host is completely down, you probably won't get an ICMP.
There is a complication here -- if the host is down completely, you won't get a 100 Trying (for UDP transport) or TCP ACK (for TCP transport), and you should be able to notice that absence quite quickly, within a few seconds. The current logic in RFC 3261 does not seem to detect and act on that situation as quickly as would be useful. Dale -----Original Message----- From: Venkatesh [mailto:[EMAIL PROTECTED] Actually, on second thoughts, you should get an ICMP error when you attempt to send the ACK to the IP/port that was down. This should result in you resending the ACK to another IP/port from the DNS list? _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
