[Freeswitch-dev] FXS bridged on FXO ports and DTMF

[Moises Silva]

Something is f'd up there badly. I cannot reproduce this in my A200.

Can you give me more details of how are you wiring things up?

Also do "git pull", I just improved the DTMF logging to aid in in debugging.
Reproduce the problem and pastebin the resulting logs.

Regarding your MWI patch. I added some comments on JIRA.
