[Serusers] t_relay to local domain?

Hi,

Not sure if this is simply a dumb thing to do or the configuration is wrong... .8.14 SER is running mostly fine.

1) SER gets an invite to 123@domain.com 2) lookup() resolves this to 456@domain.com

(serctl ul show 123 returns sip:456@domain.com)

3) t_relay is called and eventually get a 408 and the URI indicates 123@domain.com

Logging has shown that the start of route logic is never called with 456@domain.com. It seems like the t_relay() is internally sitting on the location URI. Is this intentional, to stop loops from occurring? I realize that 'aliases' would better serve this but would like to understand what is occurring under the covers.

Thanks in advance. Jim
