Prathap, That response is not sent by Asterisk. What you are most likely getting this from is a packet capture, and what you are referring to is an ICMP message sent as a backward notification by an intermediate router or host.
Basically, it sounds like the SIP UDP port (5060) on the Asterisk server (whatever its pingability) is firewalled off or access lists are stopping the traffic, either on a router somewhere in the path or on the Asterisk server itself. -- Alex -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : +1-678-954-0670 Direct : +1-678-954-0671 _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
