Hi David, H.245 tunneling is something that GnuGk leaves to the endpoints to negotiate. Its a good thing to have and with properly implemented endpoints you shouldn't have to worry about it, because the endpoints will notice if the other side supports it and switch back if not. RemoveH245AddressOnTunneling=1 will remove the H.245 address from messages, so not-so well behaved endpoints can't break out of the tunnel, but it doesn't influence whether tunneling is used or not. Also switching on H245Routed will only cause gatekeeper routing of the H.245 connection if the endpoints decide not to use tunneling, but won't influence that decision. The only switch which has a side-effect on the decision is GenerateCallProceeding=1. Because GnuGk has to send the CallProceeding before contacting the other side, it can't know if the other side supports tunneling so GnuGk has to force tunneling off when this switch is set. Lastly, there are a few broken endpoints out there that (against the spec) don't support calls without H.245 tunneling. If you are calling one of those from an endpoint that doesn't support tunneling, it won't work and you are stuck.
