[asterisk-users] Sponsored development - Monodirectional audio handling

[Edoardo Serra]

Hi Guys,
	we're needing a special implementation on Asterisk
Our intention is to contribute the development and share back the code 
to Asterisk community

Here is what we need:

- An option to Asterisk Dial command which, if used, when calls is 
answered gives monodirectional audio
(Caller should hear the called party but not vice-versa)

- A DTMF sequence (maybe handled in features.conf) for the Caller to 
start to have bidirectional audio

- When the Callers makes the audio 'bidirectional' an Event should be 
generated so that we can see it from the manager API

The purpose of thisi implementation is to deal with some carriers that 
give us the call as ANSWERED when the called party is still ringing.
Our billing software is billing the user (and the carrier is billing us) 
even with unsuccessful calls.

This way we can start billing when the user press the DTMF sequence to 
unlock audio (even if carriers bill us wrongly)

Someone wants to help ??

Regards
