Hi, I was just thinking..... I have a multi-domain setup and using domain in lookup(). However, some UAC sends the proxy address in INVITE. If all my contacts are registered with <username> and <domain>, lookup ("location") will return false since the domain in request will be <proxy ip address>..... Is there a way of reverse dns handle this or is just textops the way to go? -- mvh/best regards Helge Waastad System Engineer Smartnet
