Description:The call signalling seems to work OK, there's just no sound. It appears that the
accept call for sco_socket hangs till the call hangs up. Silence both ways.

I looked, and looked, and looked at this, but couldn't see any reason why this would be happening.  It is happening on mine too though.

I'm experiencing the same issue using a Belkin F8T003 usb adapter with a Samsung SPH-A920 cell phone.

could you test with latest addons trunk?

I tried with the latest SVN and I'm still getting what looks like proper call signaling but no audio either way. Here's the messages that appear when I enable verbose on the console after I answer the incoming call:

I did notice something if/when I pair with the OS pin is blank, however as soon as I start *, it prompts me to accecpt connection. It requires a secure (PIN). Is it posible that the call control via serial is connected but that the Audio (secure) is not paired properly???

opsys: some phones require 'confirmation' of the connection every time unless you set the phone to 'trust' the connection. usually done in th bluetooth settings menu of the phone. most nokias are like this.

could you retest these dongles and phones with the latest trunk please?
By: Steve Murphy (murf) 2007-09-16 21:12:28

Done. With the gbu 221, I am now able to both get and place calls thru the
  cell phone. Sound seems good both ways.... more testing. Happiness!

I've made a sequence of calls in both directions via the cell phone, and have not noticed any degradation in the workings of asterisk over multiple calls. (You know, like the interface getting locked up or any other such strangeness).

My reception out here in the boondocks of Wyoming is pretty poor, and it was
not uncommon for asterisk to answer the (cell) phone, and play it an announcement, which the calling party heard as nothing but loud static. I get two bars of reception, and zero if I hold the phone in my hand. It's not consistent, so I attribute it to lousy reception.

I have not noticed any side effects on the zap drivers, either!

BTW, I also have an ASUS WL-BTD201M                                                                                                                                                           dongle, and it also seems to get and place calls
without problem. It's a class 1 (100 m) dongle,
but the samsung wafer is a class 2 (10m), so....
it doesn't much matter in this instance, I guess.

murf: cool. thanks.

the static thing appears to be a 'bug' in certain firmware versions on some dongles, where the sco audio data gets bit-shifted on the way out the adapter sometimes...

im working on a fix for this inside chan-mobile.

fixed in trunk
