[Freeswitch-dev] bounty request - sofia to not route MESSAGE [was] Chat Dialplan

Mon Aug 1 05:48:21 MSD 2011

I just implemented the improvement. I've added it to the JIRA,
hopefully we can push it through sometime soon.

This is two patches I have in the JIRA. Am I submitting patches
correctly? Is there anything I should do differently? The wiki says I
should put the priority at "patch", but I don't think I have
permission to do that.
