K3765 Hangs on status:Dialing

[GoogleCodeExporter]

chan_dongle hangs with state "Dialing", even it can place the call.
No voice / apps can be activated on the call. Modem hangs.
Later, only recovery is to reset, even sometimes it can not recover.

ttyUSB0 and ttyUSB1 is realized by the kernel.
ttyUSB0 can communicate using AT commands (data is working)

AT commands work fine with misc. settings and respond well.

Things stuck at chan_dongle.c line:1201

I`ve tried using kmod-huawei-voice module. Nothing changed.

modem seems to be unlocked and voice enabled from chan_dongle. 
Even checked with dc-unlock.

Thank you for your response. 
It is quite interesting that I used this modem with its own software on windows 
machine and I could make a voicecall. 

In debug file, everything seems ok for me, as fas as I understand.
The action taken is, asterisk dials, when remote end answers dongle0 is still 
in Dialing status. Then, nothing happens on conversation and dongle0 is locked 
until a full restart, no further actions can be made on dongle. I`ve isolated 
everything at the moment and copied the debuglog, if you are interested. 
Thank you

I have the same condition with my e177. Besides, it also has the one-way audio 
problem which was not fixed with the kernel module for the e150 modem.

I solved my problem by enabling audio. Try that first.

[GoogleCodeExporter]

What do you mean "by enabling audio"?

Hi,

 Some dongles come with various features disabled by the supplier
(presumably they charge more for these options).

 You have to use a unlock code (that DC-unlocker) does via AT commands I
assume.

READ THE FIRST POST first...
This error happens on unlocked and audio enabled devices.
Don`t mess up with garbage...

I'm also affected by this issue. Could it be related to the firmware version? 
I'm running 11.126.03.06.00 on my K3765.

After an update to firmware version 11.126.03.09.00 my K3765 works flawlessly 
with chan_dongle.
