[Asterisk-Users] DTMF Caller ID w/o polarity inversion

[Renato Mintz]

Hi Folks,

I've been looking around and found some references of some Caller ID
patches (Mantis bug#9) for X100P and TDM400 for Netherlands, Sweden
and UK. It's been quite hard to understand what has finally been
incorporated to the distribution (if anything) or which patches must
be applied in witch snapshot of the repository.

I've tried some different approaches but nothing worked and my
question finally is:

Is there any implementation for X100P or TDM400 that supports DTMF
caller ID WITHOUT the need of polarity inversion before the DTMF
spill? Is anyone working on this? This is the way it works in Brazil
and some other coutries...

Thanks a lot,

Renato
