[Serusers] Greeting, and Request for help on incoming "Strip" Command

[Klaus Darilion]

Hi Ian!

Don't mind the To: header, the request URI is the one which will be used 
to route the call. Use strip(6) to strip the first 6 digits. Then you 
could use lookup("location") and disabling use_domain in the registrar 
module.

Maybe aou could use rewritehost() before lookup (don't know if lookup 
uses the original request URI or the modified one).

regards,
klaus
