Review request for Asterisk Developers.
Bugs: ASTERISK-22962
https://issues.asterisk.org/jira/browse/ASTERISK-22962
Repository: Asterisk
Description
-------
When creating channels via ARI, the current code fails to provide any default
format capabilities. For non-virtual channels this isn't really a problem - the
channels typically receive their capabilities as a result of the underlying
channel driver configuration. For virtual channels (such as Local channels),
the lack of any format capabilities causes the Asterisk core to make some 'odd'
choices with respect to the translation paths. The issue reporter had some
paths that had 3 hops on each channel leg, causing multiple transcodings and
some really crappy audio/performance.
By specifying a baseline of SLIN, we prevent that from occurring. Note that
this is what AMI does when it performs an Originate, as does res_clioriginate.
Note that this does not solve the odd translation paths that were created or
some other more deep performance issues in the translation/format capability
core. Those should be addressed separately of this problem.

Testing
-------
Without this patch: bad audio, bad performance.
With this patch: acceptable performance/audio.
Thanks,
