Subject: mod_rayo: add new config pause-when-offline - will pause inbound calling if there... 
X-Git-Tag: v1.2.23~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=818bf3c6e315d2e53d0b1a3a0c41ab0601b2c2ba;p=thirdparty%2Ffreeswitch.git

mod_rayo: add new config pause-when-offline - will pause inbound calling if there are no online clients to handle calls.  This is useful if you want FS to respond 503 to options ping when there are no online rayo clients.  Default behavior is to disable this param.
