Any and all feedback on this thread would be much welcomed.

We always disable ALG on the client side where possible. It always seems to break the connection. We also have the offsite phones register via tcp instead of udp and that helps. You may also want to look at your keep alives and set them to around 20-40secs or so to keep the connection open with the server.

We have had good success with the opensource softphone jitsi.
