Subject: [PATCH] Fix DTMFs once and for all

Stopped rewriting the raw RTP DTMF data, hoping the phones are
generating them properly (most seem to be frankly)
Enabled the CISCO and SONUS workarounds by default since they usually
don't do harm but do lots of good.

This fixed our ability to work with Avaya systems
