[Serusers] Serving Multiple Domain in one SER.

you can use some prefixes to distinguish between domains. Ex:
Domain1 :sip1.mydomain.com / Prefix: 91
User1 : 1234 at sip1.mydomain.com
and
Domain2 : sip2.mydomain.com / Prefix: 92
User2 : 5678 at sip2.mydomain.com
When user 1 wants to call user2 he has to type: 925678. In you config
file, based on these prefixes, you can make decision where is the user
registered. To remove the prefix you can use the strip() function and
rewritehost() to change the domain in the R-URI.
if ( (uri=~"^sip:92[1-9][0-9]*@sip1.*"){
log(1,"request from sip1 for sip2\n");
strip(2);
rewritehost("sip2.mydomain.com");
};
