Thank you for your answer. "are you doing something explicitly to send the DTMF"No. I just press buttons in my cell phone (I mean startpoint). In my opinion it is strange. I make answer() in lua script and use session:getDigits(). All works fine.In the end of script I use execute_extension which implements bridge.session:execute("execute_extension", "".. recieved_digit .." XML ".. user_context .."") Thus the call was answered in lua script. Next the call go to endpoint. How dtmf must be transmitted in this case ? Why I have not issues when I call from sip devices? Any help are welcomed. Thanks.

I just ignore the dtmf, and when FS bridges it sends the call on properly. -Avi 2011/11/1 Yuriy Nasida <nasida@live.ru> Hello community, I have some issue with delivery of dtmf.The call flow is: one sip provider - FS - second sip provider - endpoint which expects correct dtmf On FS I have simple custom lua application which implement logic of calling cards system. I have not issues when I call to lua application. I can enter destination number (by using dtmf apparently) and all works fine. But when I try to send dtmf second time for endpoint which expects correct dtmf I have issue with double dtmf. It is noted that when I call from sip device I have not ANY issues. But I have issue when I call from any cell phone or landline phone. Any ideas are welcomed. Thanks.
