Versions:Frequency of
Description:We tested several times and it always happens the same way.

If we use nocallsetup=yes we have great audio, but... false answering supervision. The mobile phone calls the number and asterisk sais the call is connected even when the phone is still ringing, we also have false disconnect supervision, so when the call is hung up, asterisk sais it is still connected.

If we comment the line ;nocallsetup=yes or we take it away, answer supervision  and disconnect supervision works great but audio is choppy and also there is delay in one leg of the call.


-Asterisk Version: 1.6.1
-Addons Version: 1.6.1
-S.O. Debian/Ubuntu 9.04
-Phone Model: Motorola i776  Motorola┬┤s Blue tooth seems to be the best for   chan_mobile according to our tests, (tested nokia and sony erickson ).
-USB Dongles : Generic compatible with Bluetooth 1 and 2   (We tested several of them chan_mobile seems to work best with dongles compatible with bluetooth 1)
-Number of phones: 4 (blue tooth Hubs dont transmit audio unless placed in a group, USB PCI cards work great).

if you set nocallsetup=yes then chan_sccp has no way to know if the call is connected or not. Thats why your are getting your false answering supervision.

Is the audio really getting better when setting nocallsetup=no? Can somebody verify it?

if we set up nocallsetup=no audio gets better.

the way we could fix this is installing trixbox 2.8

now everything works ok.

Try testing with asterisk trunk or 1.6.2 without nocallsetup and see if your audio quality improves.

Thank you for your response, we tried asterisk trunk and audio is fixed, now we have the problem that phone disconnects in the middle of a call
