[Asterisk-Users] looking for failover ideas

[William Lloyd]

Can you post or email your patch can I take a look at it?

It's specifically the issue of NATD that I'd like to be able to know  
what asterisk host a phone registers to.  that way I can do an  
asterisk to asterisk transfer and the original asterisk host that the  
phone is registered to can pass the call back down the NATD connection.
