[Users] Usage of record_route_preset / dispatcher / UAC-Module

[Carsten Bock]

Hi Everybody,

I hjust wanted to mention, that i fixed the problem myself.
It worked fine, after i defined an alias with the loadbalancer-IP. I 
just looked into the sources and found a hint, where to look! OpenSource 
is great!
Anyhow, thanks for a great SIP-Router!
