All,
    I am newbie to SER.Here has a question.

    I have three SIP-client(MSN messenger4.7 and kphone) and a proxy server-SER.
    Three clients all register to SER.
    I uses messenger4.7 to invite the other one .When invite message pass through SER, I rewrite URI to kphone.
    But this doesn't work.Followed my script.How should I do  this work?

    Thanks.
