Hi All,

(Git head build last week on centos 5.n)

This is a new one for me.  Calls IN to the new customer with Cisco phones behind NAT are working, but not outbound!

I have not been to the site yet.  I am told that they can call out once or twice then have to reboot the phone to dial out.  Dialing in continues to work!  one person says the phone says “Call merged”  another says it say “Request merged” on the phone display!

I did see in the logs, that when it works, we get:

Can anyone shed light on what’s happening “at that particular juncture” and how I may go about debugging it?

I was thinking FS was not finding a connection through NAT to phone, but then why do incoming calls work?

Thanks in advance,
