Summary:                    Mobile connection is broken after 40+ minutes
(asterisk hangs)
Description: 
When i use the chan_mobile asterisk module this works great but there are
serveral problems after some minutes:

- If you receive a inbound call from the cellphone to asterisk this works
well. But after some time you get a higher delay and this delay is growing
in the same call. (First you have no delay from the cellphone <=>
asterisk).

- After 40+ minutes, when de sound delay is very high (2 seconds) the
connection hangs and becomes silent.When you get this problem, asterisk
hangs and it is not working to receive a new call and also CORE STOP NOW
doesnt work.

Is there anybody who can resolve this problem. 

I try the following options, all without a solution:
- Reinstalling Asterisk (serval versions)
- Use different 2.6 kernels (from ubunto interpid,hardy, debian sarge &
etch)
- Different CSR dongles (with Bluecore 2,3 and 4)
- Disabling ehci_hcd (modprobe -r ehci_hcd)

I'll try asterisk/chan_mobile again with Bluez 4.28. There is more
stability.

But the audio from asterisk to the cellphone 

I think there is a big audio problem:
Audio from asterisk to the cellphone works well with all the bluez
versions.
Audio from the cellphone to asterisk is always delayed, but in the new
bluez versions it is the delay smaller (but not useable).

Maybe that we can rewrite the chan_mobile for transporting audio from the
cellphone to asterisk. The bluetooth dongles accept ULAW or ALAW if you
change the class from bluez.

Anybody who can help with it??
