Another bit of info – we did a packet capture on the line and the iwatsu system is sending a BYE command at 30 seconds which is disconnecting the call. There is basically no traffic on the line during the outbound call. Inbound calls you can see traffic between the two systems. It seems like to me that when making an outbound call, it isn’t really talking to the iwatsu system and so the iwatsu system closes the line.
