[asterisk-biz] Solving DTMF issue

The simplest solution is to just use a provider that implements this
properly.   I know our providers (big international networks) all
support this with no problem, if you are seeing many different types of
DTMF you likely have a very broken reseller in the path...

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
