New Revision: 421664
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=421664
Log:
Trying to understand the old transmit_register() function. Some of the things
here
are a mystery. In order to add proper DNS srv failover and lookup a lot of stuff
needs to be re-ordered and changed.
Also implemented a flag that indicates that someone configured a port number. In
that case, SRV should be disabled. That part is a bug fix I think.
