Need help with SIP also... I'm to stupid I belive :(

Hello there from germany,

and at 1st excuse my ugly english, pls…

I try to setup the SIP, enter all the needed information and the test goes green. Looks like all is ok. But if I activate “phone enabled” the server hung on “Registering” at the “SIP Phone Mappings” - site.

I run it on a WIN2003x64 (WAN, VPS at “Host Europe”: http://www.hosteurope.de/produkte/VPS-Windows ) and I belive that’s a problem of the firewall, but I don’t know / not shure witch ports I have to open for incomming requests the SIP-Server need to connect back…

So can anybody show me the right way?

Greetings

Micha
