Greetings. Thanks for the response!
I am using 0.6.1. It's easy enough to try the latest 0.6.2 version, so I will pull that down. Single-homed. I do have a 2nd external interface, but I've taken it down to reduce the problem set at the moment. Static ip address. Firewall configuration on the single EXTIP: EXTOPEN="t22 t8088 u4569 t80 u5060 u10000:20000" I've got to go back to the rtp traffic streams and make sure that the rtp port(s) are below 20000. Thanks again.

I have not seen an issue with the net5501 failing to handle the RTP stream, my issue is that on ENUM calls Asterisk is attempting a "native bridge" with my NAT/firewall/router does not allow. Anyway, are you using 0.6, 0.6.1 or the latest 0.6.2 release candidate which I think is labeled as astlinux-0.6-2082 on http://www.djhsolutions.com/astlinux/ Also, are you running "single homed" or do you have multiple interfaces online? How is the firewall on your AstLinux box configured? --Tod On Nov 21, 2008, at 8:58 AM, Ron Byer Jr. wrote: > I've started using the astlinux 0.6 on a net5501 in earnest > recently, and we have found ourselves in a world of hurt from a NAT > perspective.
