[cisco-voip] FXO hang due to connectivity loss?

[Norton, Mike]

Are you sure that the gateway is properly detecting the tone and hanging up when connectivity *is* working? FXO disconnect is terribly hit-and-miss even at the best of times. Disconnect supervision on FXO is more of a best-effort attempt than an actual thing.

If the disconnect signal is properly interpreted by the gateway then like you I would expect the gateway to end that leg of the call regardless of SIP reachability. But I consider that a pretty big if!

Hi Folks,
If the voice gateway is defined with disconnect tone/ cadence,etc. Should a loss of connectivity (SIP signaling between VG and CUCM) cause the FXO port not to hang up ?

To me , SIP is peer to peer signaling. It should not affect the voice gateway decision for going on-hook when a disconnect tone is detected even there is a loss of connectivity to CUCM.
