Hello,

the problem is in if (uri=="fly.superman.com") condition. Since you do not use regular expression matching in the condition, it will match only Request-URIs that contain _exactly_ "fly.superman.com". But if you look at your Request-URI you will notice that there is "sip:fly.superman.com" (notice the "sip:" at the beginning) and therefore the condition will not match.

The server will forward the message again to itself...until maxforwards check hits.

Replace the condition with if (uri==myself)

Jan.

PS: The condition you are using probably doesn't do what you expect. I guess you wanted to match Request-URI containing "fly.superman.com", to achieve that you should use something like this:

if (uri=~"[@:.]fly.superman.com([;:].*)*")
