Hello,
This is just to confirm that if you have a Cisco PIX Firewall sitting
between your SIP Proxy (eg SER) and your PSTN gateway (in my case a
Cisco AS5350) you need at least version 6.3 of the PIX IOS. There's a
nasty bug in versions <= 6.2 which prevents transactions to be correctly
established by blocking SDP packets.
Maybe this will save someone else time
