Yes, i am positive that i get a new dialtone from the GSM Gateway.

If i dial DTMF codes from a SIP phone connected to Asterisk, i can see the
digits appear in the display of the GSM Gateway. But it is a bit
incovenient to call an internal extension, wait for the dialtone and then
punch in all the numbers of the cell phone i need to call.

I would prefer Asterisk to decide where / how to route the call and send
the DTMF inband to the ATA device.

Thanks!!
