----------------------------------------------------------------

CLI output from a relatively simple example.

I suspect the issue stem from the fact that normally a Local/ channel will derivc it's format from the channel creating it (parent channel?), which will then just end up doing a simple pass-through.

However, since app_originate originates the channel using SLINEAR format, this prevents to the end-points from negotating the format to use properly and ends up forcing translation via slin, even when the two formats on either side of the Local channel are the same.

In my opinion the Local channel should adopt whatever format gets set up for leg1 of the Local channel in this case, and not SLINEAR.

If someone can push me in a direction I'll be happy to try and cook a patch, however, I have no idea where to start with this.

> The simplest example of this is with a SIP and an IAX2 endpoint available, eg SIP/102 and IAX2/upstream, both configured with disallow=all; allow=g729 with codecs from digium loaded.
> cli> originate Local/102 at aanswer Dial IAX2/upstream/number
> once connected a g729 show licenses will show that two encoders and two decoders are in use.
