Hi all,

I'm a newbie and I've been searching through the entire mailing (including www.onsip.org) for a solution regarding landing of calls to a Cisco 3600 GW.

I've configured my SER based on the "Getting Started for mediaproxy" document found on www.onsip.org, and it worked great between UAs. Based on all the info I've found on this list + suggestions from others, I came up with the following config file. I've managed to have the UAs to dial out via the cisco, yet once the PSTN side picks up, no sound could be heard (both ways). I know the Cisco is working for sure, since my friend is using AUVTECH SIP Server and is landing calls properly via the same gateway.

I'm greatful for any help on this issue!!
