Re: no voice transfer on either ends


how the tunnel is configured ?

I'm not sure how the phone is registering, but a remote location is supposed to have a different IP subnet. In that case you have to configure "mtp" under "ephone" for the remote phone.

Hope this helps, please rate post if it does
