[Freeswitch-users] Why does a SIP forked dial select just the first 183?

[Brian West]

Disable 100rel on the sofia profile or update to latest SVN trunk.  We  
have an issue on jira about this already and are working with the  
sofia team on this issue.  The solution is to disable 100REL and it'll  
quit doing that.
