Description:I've made some coding/patching of Asterisk 1.4 backport of chan_mobile.
Now I have SMS for both directions in PDU mode with encoding conversion to/from UTF-8 on Motorola L6.
Have dropped audio connection issue while SMS received during a voice call, maybe there is a need to extend the state machine to shift incoming SMS processing to the end of voice call - this may be the simpliest way to solve.

Also fixed mobile reconnection when remote party on mobile hangs up first.

There are still two big problems:
1. DISA/IVR doesn't work - packet syncronization issue I think - haven't digged it yet.
2. Noticeable incoming audio delay when call originated through the mobile; there is no delay if call is received by mobile.

If anyone interested I can send patched file(s) by e-mail.

Same audioproblem also with L6 (delayed audio, only on one way)

Some other issue's in relation with your problems:
- DTMF is also not working with the READ command (read dmtf digits) (when you answered the call with asterisk from cellphone/for low cost routing).
- The audio delay is higher when you make long calls (10+ minutes)
- Sometimes distortion with incomming cellphone calls

Can we resolve this problem?

Yes. I am working on (or will work on) these bugs.  Please open a separate bug report, or comment on an existing bug report if those bugs have already been reported.

@mnicholson is there any patch for chan_mobile ready (for detecting dtmf,sound problems etc)?  I add all the problems also to the now open bugsreports.
I think all the problems are audio problems....

If you need more info, to help you with resolving this problem, ask me!!
