Yes, thanks for that thought Tim,  although I think they fixed that  
"feature" in the latest firmware update.  It definitely seems to be  
some sort of realm realated issue (I think)...

I am thinking that if I could get my router to properly resolve the  
name (ie sip.domain.com) into the internal number (ie 192.168.1.101)  
then my issue would be resolved.  I even did attempt setting up a  
seperate DNS for this lookup,  but the stupid phone caches DNS info,  
so that when I leave the site, it continues to produce the (now  
wrong) internal IP address.

Ugh.  I think I am going to try playing with the SIP debug settings  
in asterisk and see if that gives me any additional help on figuring  
out what is going on...

Another solution would be to run and entirely seperate asterisk for  
the LAN, which had another realm name....  That seems insane though.

Oh well,
Marty
