It worked!!!!

Here is how i did it in FreePBX :

1) Setup a SIP extension for the ATA device, in my case i give it 
extension number 298. Edit the extension after creating it set DISALLOW to 
all and set ALLOW to alaw to make sure DTMF sending will work.

2) Create a custom trunk, and set as Custom Dial String :
Local/$OUTNUM$@custom-gsmvoip-out

3) add to extensions_custom.conf :
[custom-gsmvoip-out]
exten => _.,1,Dial(SIP/298,,D(wwwwww0${EXTEN}))

Note that i put a leading zero there, because for my fallback outbound 
routes i needed to strip the leading zero so i added it again here.

4) Insert the custom trunk in outbound routes

That's it

Hope this will save somebody else 2 days of frustration :)))

Cheers!

Yes i did, looks like an excellent product with many, many features and 
of outstanding quality.

However, given the cost of that unit i would have to be calling mobile 
phones 24 hours per day for at least the next 10 years of my life to 
earn the investment back, so definatively economically unviable.

But thanks for the tip :)

Dear sir,
 
what about receiving call from a GSM gateway. I didn't see the caller ID?. 
is it happen to you? and what is the solution,Please.? 

thanks,
Belal
