Hello Excuse the delayed response. If using 4.0.1, I hope you have applied the binary patch. http://track.sipfoundry.org/secure/attachment/20745/patch8.zip > Have you taken a look through wireshark?

It is possible that you do not have symmetric relaying on your firewall. The auto attendant is based on freeSwitch which will only recieve packets from where it has previously sent packets and vice versa. So you must map 1:1 external port maps to identical internal port and vice versa. Turn off any kind of port randomization. Please have a look at http://sipx-wiki.calivia.com/index.php/SIP_Trunking_with_sipXecs:_Overview_and_Configuration#How_to_configure_sipXbridge For firewall and NAT configuration tips.
