[Users] Forward requests based on userid

Hi folks, I wanted to route sip requests based on user id with it's appropriate Gateway IP address which is stored in Mysql database , is this possible? Database structure: userid,gateway 617978XXX 64.80.XXX.XXX 78189XXXX 64.100.XXX.XXXX example: if someone call 617978XXX he will be routed to it's approriate gateway at present I am using static route like: if (uri=~"^sip:617978XXX@") { rewritehost("64.80.XXX.XXX"); } if (uri=~"^sip:78189XXXX@") { rewritehost("664.100.XXX.XXXX"); } etc,.... I am afraid the config file gonna get larger if I add more than 500 users(DIDs), I am looking for an alternative to store DID numbers in database (Mysql or text) and route them accordingly with the appropriate Gateway address. Thank you so much and I will appreciate if you can help me out! Ben __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
