Hi... i got the p[oint of using domain table i am already using it..that is to check for multiple domain verification only.....but for eg...if i add two users with username 111 with domain as a.com and b.com....it does in subscriber table with username as 111 and domains as a.com and b.com....this all is fine....when 111(a)a.com tries to call like 111#...what will happen...call only goes for last registration done...coz in location structure , it doesn't add the latest entry of 111(a)b.com.... whenever u make a call it searches for the first record in location table and call goes to it...so 111 a.com 111 b.com if the entries are like this....b.com can call a.com but not vice-versa... _________________________________________________________________ Play the prediction game on MEZ.
