[Iaxclient-devel] iaxComm PATCH: codec indication and selection

[Richard H. <rh...@le...>]

Hi,
  I'm new to VoIP, but I've been experimenting with iaxComm on linux.
I wanted to control which codec was used without having to change my
asterisk config each time, so I came up with this patch.  It does
two things:

1) On the display, after the remote party name, if displays the codec
   in use for this call.. e.g.    asterisk/4567 [ULAW]

2) It adds a preference tab to enable specific codecs.  This offers
   SPEEX, GSM, ALAW, ULAW at the moment, all enabled by default.  It
   sets the preferred codec for a call to whichever is the first enabled
   one in that list.

To get the codec in use, I enhanced struct iaxc_ev_call_state to include
a format field.  That may be a problem if changing the library interface
is not allowed.  If so, maybe there is some other way to get that info,
or we could add a new library function to request it.

Anyway, let me know what you think,

(not on the list, so please cc me on replies)

Thanks,
  Richard
