I have a pix 501 running version 6.3(1). I am having issues with my IP Phones behind teh PIX. The Phones register fine with CUCM 7.13 but I am getting 1 way audio. I have verified this is not a routing / ACL issue. I have attached my config, Any ideas? I think it may be a protocol issue, but not too familiar with the PIX configs.
Thanks

After a long day of troubleshooting with TAC, it appears this may be a Phone issue. This setup is working at one
site with a 7960. I have a 7965.
After troubleshooting, we found the 7965 registers with the NAT'd address obtained by teh VPN client, but during call setup, the Call setup is using the local 192.168 address which is not routed back to me. Very strange, but TAC believes it has to do with changes to SCCP on newer firmwares.
My IP Communicator runs fine behind the PIX.

FIXED.
Downgraded to the 8-3-2s firmware and the phone is now working.
How do I give myself some star points ??
