I've a CCM 6.x and some GWs using H323 to access PSTN. I've a problem on SCCP Phones when a call is established to cell phones through PSTN using the H.323 GWs.
The problem is that I don't receive the disconnect from GW when the cell phone ends the call. When that happens I hear fast busy on phone, but call is still open on phone. The timer still runs until you on hook the phone.
I've experimented the same problem with FXO and E1 PRI, controlled via H.323
I've checked another deployment using MGCP controlled GW, and when the cell phone ends the call, the ip phone stops the call ok.
There si something to adjust on GW or CCM config to receive the disconnect?
Please let me know.
