Details - I am experiencing an issue with Kamailio 1.5 and the Dispatcher module.  

I have 2 network cards

eth0 - public network interface.  I actually have eth0 and eth0:1 with two public IPs bound to the interface
eth1 - private network interface.   


The issue is that when I do not explicitly specify the "listen" configuration parameter, all my dispatch destinations NOT on the same public subnet get stuck in "P" state and never have calls routed to them.  I have two datacenters which house racks of asterisk servers.  My carriers send all SIP traffic to my primary SIP gateway, which then distributes the INVITE requests across the public internet to distribute the load between my two facilities.  If I leave out the listen statements below, the asterisk servers outside of my 208.X.X.X network won't receive calls.  When I include those lines, everything works fine.
