[Asterisk-Users] IAX2 + port translation
Hi all, I'm having trouble with incoming IAX2 calls on 1.2.7.1 - mostly they work, but sometimes the caller just gets dead air or disconnects. IAX2 debugs show HANGUP and INVALID codes in these cases, rather than a proper RINGING transaction. My firewall is doing NAT, and changing the source port from 4569 to something else - my IAX2 provider suggested this might be a problem. Is it? Should this work: steerpike*CLI iax2 show registry Host UsernamePerceived Refresh State 64.26.157.230:45698886708729 64.26.155.62:14353 60 Reg 64.26.157.230:45696134827945 64.26.155.62:14353 60 Reg 64.26.157.230:45696136866597 64.26.155.62:14353 60 Reg 64.26.157.230:45696136866675 64.26.155.62:14353 60 Reg There are four DIDs, and all are registered to an odd port (14353). Is this OK? (I am using a Sonicwall TZ170 with Enable Consistent NAT on). - Mike ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

You server is registering to your provider on port 4569 as it should. Their server is seeing you register from 64.26.155.62 and using the prt 14353 which is the port that your firewall has given that outgoing connection. Possibly that the firewall is removing that connection port after some time and your provider cannot get back to your box? Try setting the reregistration time lower than 60 and see if it helps. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Hmm, it looks like I have to edit channels/chan_iax2.c to lower the registration timeout - I'm trying 15 seconds, and we'll see if that makes a difference. (You have to override the provider's requested timeout of 60 seconds). Does anyone have any idea what the IP/port PAT pair timeouts are for the Sonicwall TZ170? I see that someone had a similar problem (PAT timeouts, on an unknown device) here: http://lists.digium.com/pipermail/asterisk-dev/2005-February/009341.html - Mike ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
