Hi Everybody... Continuing the litany of problems I'm experiencing with my new system I'm getting issues connecting between SIP phones. A bit of background... I have an asterisk server running in a central location where I have two incoming analog lines connected to FXO ports, two analog phones connecting to FXS ports and a single SIP phone. In addition I have a remote site connected via a CIPE VPN (ok..ok I know it's not a real VPN...) with a single SIP phone. Calls initiated from the remote SIP phone to the central SIP phone often have trouble... the user of the central phone cannot hear anything from the remote phone although everything is heard at the remote phone. If the remote phone calls either outside or to one of the Zap phones there is no trouble. If the local SIP phone calls the remote SIP phone there is no trouble. Both phones are from the same vendor, have the same firmware and the same configuration with the exception of phone number, PIN, IP address etc. What am I doing wrong here? Ian

I had a problem with SIP in ver.1.0.7 and 1.0.6 so I'm still on 1.0.5 -- #Joseph
I'd personally be using Ethereal to look inside the SIP messages for the SDP info and checking the source/destination of the resultant RTP stream. One-way audio is typical of NAT issues. Although you are running a VPN (of sorts) I suspect that your SDP messages are getting screwed up somewhere. What are the asterisk NAT settings in effect for each of the SIP phones? I'd be inclined to turn them both ON to ensure that symmetrical RTP in being used. Also make sure that canreinvite is OFF for both. ----- Original Message ----- From: "Ian Pattison" <ianp@technologyassociates.ca> To: <asterisk-users@lists.digium.com> Sent: Thursday, April 07, 2005 4:49 AM Subject: [Asterisk-Users] SIP - SIP Problems Hi Everybody...

Don't ask me why but I've got some limited connectivity now... I initially disabled "canreinvite" and enabled NAT on both phones. They connected to * just fine but when I attempted to make calls I received no audio on the remote phone... can't say for sure on the local one. I then disabled NAT on the remote phone only and was able to make a 2-way voice call to the local phone (although it did take about 2 seconds for audio to kick in...) from my understanding of the situation this config should not work at all. Packet decodes are my next step... has anyone here ever successfully had Ethereal running in text-mode only? My * box does not have X installed and is only accessible via SSH.

Removed NAT from both phones but left "canreinvite=no" for both. Looking better.>>> ianp@technologyassociates.ca 07/04/2005 09:23 >>>Don't ask me why but I've got some limited connectivity now...
