Thank you for your help on this issue Found the issue was incorrect location and missing items
Missing: Alias="blah.com" Alias="sip.blah.com"
The following was located in the wrong place.
lookup("aliases"); if (uri!=myself) { route(1); break; };
This needed to go after :
consume_credentials(); };
Not after :
if (uri=~"^sip:[+|00][0-9]*@") { # International PSTN All other countries route(4); break; };
