Hi there, Is there any way to use expressions in the route configuration? I'd love to use something like: if(uri=~"sip:([a-z])+@thirdtower.com" && !lookup()) { seturi("sip:voicemail@thirdtower.com/$1"); } Which would mean "if someone calls to "sip:someone@thirdtower.com" but "someone" is unknown / unregistered, forward to "sip:voicemail@thirdtower.com/someone". Greetings, Sybren -- The problem with the world is stupidity.
