Matthew, allow=all is defined in sip.conf for the ITSP's SIP peer. Additionally, ITSP supports g729 codec as we are able to send the traffic from other soft switch. In case g729 on asterisk box, as I mentioned earlier, call even doesn't go out of the asterisk box. Below extracts from log also indicate the same thing.
