Hello,

I'm thinking about using freeswitch as a core for a softphone and for this I would need to know some things.

- Is there a plan to make a jitterbuffer for FS in foreseen future? - Is there a plan to make a software echo canceler (especially for mod_portaudio)? Packet-loss canceler? - Is it possible to use speex's echo cancelation?

Yes, but it is not implemented today.

- Is there a plan to use the advanced features of the speex codec like VBR, quality?

Not plans, but discussions.

- Is there a plan to move to speex-1.2beta1?

Yes, unless I don't get it done in time before the 1.2 release is rolled. I have been waiting for the codebase to calm down a bit and was going to look at all the libs and see what needed new versions, unfortunately the codebase has been very active for a few months running now, so I have not done it yet. Speex particularly the developer asked us to try that versions and test it out, so it is at the top of the list.

- RTCP for quality measurement?

None in there now, no reason it couldn't be added. I would want a way to disable this when not needed so it doesn't chew up the extra sockets.

- Is it possible to compile everything into one binary file (elf/exe/etc.)?

Discussed, we have not attempted, this would take some rework in the module loader, and we would need some sort of magic Macros to make this "easy" to do. I would love to see this, especially for embedded platforms, it should allow us to more aggressively optimize the code as well. There are some licensing implications with all the LGPL code in use (see the LGPL lic for details) but that is not a concern of mine, as we already dist all the source-code anyways.

- How to use sRTP?

I don't think we put the negotiation for this in sofia yet, you can search to be sure, it was originally implemented in exosip before it was abandoned.

I know that those are not easy questions and the paypal button might help to accelerate, I'm just curious what are the plans, thoughts,

etc.
