Subject: Add new AMI command LocalOptimizeAway.
X-Git-Tag: 11.0.0-beta1~2787
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c6b7eae5e68a79ef99cb735e3848c7e078d261ac;p=thirdparty%2Fasterisk.git

Add new AMI command LocalOptimizeAway.

This command lets you request a "/n" local channel
optimize itself out of the way anyway.
