phone "a" is conected to pbx "a" and this to the to router "a" via fxo. router "a" to router "b" via voip, and router "b" to pbx "b" via e&m and pbx "b" has phone "b".
The fxo on router "a" remain connected until phone "b", hung up. But if I make a call and phone "a" hung up, the router "a" remain connected until phone "b" hung up.
I run the debug voice ccapi inout on router "a" and I can?t see when phone "a" hung up, only when phone "b".
