Guys, I've been poking around trying to find a good answer for this via voip-info, google, etc... Haven't found anything that helps, so maybe you mates could. A lot of my customers are using Linksys UAs (router/ATA PAP2) and some using Sipura SPA-2002s. Every once in a while, the customer will get one-way audio. I've read that this is commonly caused by the outgoing RTP port not being the same as the incoming RTP port. A lot of other devices (I found info on forcing Xten to do it) can be forced to use the same port for both, but these devices don't have an option (that I've been able to find, even in the provisioning configs) to do this. So, my question is two-fold: 1. Can Asterisk be told to send the RTP stream for incoming and outgoing always on the same set of ports? 2. Does anyone know something that I'm missing for the above mentioned devices? They're all the 2 line version of the ATA and/or router configs (wireless and wired) Thank you all in advance for your thoughts and comments. I apologize in advance if I missed something that was publicly available. Sherwood McGowan -------------- next part -------------- An HTML attachment was scrubbed...

[Asterisk-Users] Asterisk and RTP streams (just bumping)
Bumping, just in case it got lost in the shuffle today... I think this is an important thing to be able to do.

Sherwood, I have never known the RTP audio to be on only one port in sip. I believe it's always on 2. The one way audio is always a nat/firewall problem in sip.
