I have had this problem several times and so far no resolution. However for me it has always been with IAX. I have been told that IAX is supposed to be NAT-safe but that does not seem to be the case for me. For example: SIP (grandstream, snom) ->Asterisk->NAT->Asterisk->SIP (grandstream, snom) He can hear me but I can't hear him. In another case I had: IAXclient (soft phone)->NAT->Asterisk->Snom And I could hear him but he could not hear me. Same phone system and settings as above. However as soon as I switched the first users phone to talk directly to my Asterisk box with SIP it worked perfectly. And when I switched the user in the second case to a SIP based soft phone it also worked just fine. SIP has worked better through NAT than IAX (with nat=yes in sip.conf) which is bizarre and contrary to what I have read where IAX should be NAT-safe and SIP not. I have dreams of a world fully converted to IPv6 where NAT no longer exists. Alas, it is but a dream. -- Tracy Reed The attachment is a digital signature. http://copilotconsulting.com More info: http://copilotconsulting.com/sig _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
