You haven't described exactly what you're doing, so I dunno..

Other iax2 endpoints should honor our preferred codec when we make 
calls.  When calls come in, we will use the other side's preferred 
codec, if we support it.  I've written about that algorighm already, but 
you can see it in the code.

You could write one.  It would be about 3 lines of code -- I'd accept a 
patch for it.

Described above, and earlier.

You don't need to set the min framesize here, it will always do the 
right thing anyway.
