[asterisk-biz] Feature Bounty / Consultancy: Stereo support for MixMonitor

[Alexander Lopez]

The out of sync issue happens when the call legs start at different times.

The solution to this is to reverse the two files as the end times are exact.

Merge the files one on each side or a stereo mix,

And then reverse the mix.

Subject: [asterisk-biz] Feature Bounty / Consultancy: Stereo support for MixMonitor

Hi,

We would like to add stereo recording support to the MixMonitor application but don't have any C dev resource / experience in our company. Only PHP, Java and .Net but might be able to contribute some form of assistance if only testing etc.

The intention is to have each party on a call as a separate audio channel.  Happy to limit to two party calls and not conferences etc if that helps reduce scope.

Could anyone recommend the best place to post this request, if it's not here, or have any first hand recommendations of contractors they have used for similar projects?

We are unfortunately stuck with using MixMonitor rather than Montior due to a few issues:

A) We are using FreePBX to control the dialplan and that requires MixMonitor without custom PHP dev work.

B) When researching feasibility of customising FreePBX to use Monitor we tried to getting MixMonitor to output separate files came across issues with the two audio streams being out of sync. This was by using the 't' option in MixMonitor.  Maybe this is truly a bug and really what we should be focussing our efforts on.

The feedback from FreePBX community seemed to be that switching to use Monitor would be very difficult.

I've read through a fair bit of the code and think I know what areas need extending / improving.  For example the bug with the separate files seems likely to be around line 329 of audiohook.c.

Many Thanks

Alex
