I'm having a little trouble with multiple OpenSBC boxes. Registration through to the sipXecs system behind both of them works great. But if a user coming through one of the SBC's tries to call a user on the other SBC it's like that user isn't registered to the sipXecs system... call just goes to VoiceMail.

It's possible I have something blocked on Vyatta (basically everything allowed outbound from a firewall perspective but unbound from the Internet side only Port 5060 tcp & udp, ports 10000 - 20000 udp are allowed in.

Here's my config file.
