[asterisk-biz] Solving DTMF issue

[Cyriaz@Gmail.com]

I would like to hire an expert who can absolutely fix the following issue:

I have SIP providers who sends several DTMF mode to my asterisk at
different times. We have changed "dtmfmode=auto" and still sometimes
it recognized dtmf and sometimes not. I need someone to identify the
issue and detect all DTMF mode sent by the SIP provider no matter what
it is and pass it to asterisk without any problem.

Thanks
