[Freeswitch-users] double dtmf

[Yuriy Nasida]

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.
