Hi All I have 2 phones registered to an asterisk server. The phones are sat behind a NAT. If I have the asterisk sat inline on the call after setting it up (with transfer option specified as an example) the call works fine. If I take out all options so the asterisk should bridge the call and hand it off I get the phones ringing and then when the call is answered there is no media. I know this is probably somehting related to the NAT as to why the asterisk cant handoff the call but was wondering if anyone else has been able to over come this at all? Many Thanks SP
