I like to call my server/phones from outside my lan without register a client

I guess the first question is why do you want to do this?

If you really do need to do it then you are going to have to manage NAT traversal yourself and this is not trivial when using SIP and RTP to move traffic back and forth.

Hi,

Excuse my English maybe it was a bad explanation ?

Other People should be able to call me via Internet without any registration (not on my server or other carriers), they have only a pc with internet-connection, i dont like to register ther clients on my server. They should just open a Softwareclient like EKiga and make a connection to me.

It's not easy to do what you want to do unless the phones have their own public IP addresses or you use some mechanism for NAT  traversal.  Asterisk, and most carriers, use a technique called Symmetrical RTP with a NAT heartbeat/keep-alive.   You can also use STUN servers or a remote SIP server with Session Border Control (i.e. a carrier).  Some softphones have mechanisms that can help but the techniques need to be the same on both sides.

Good luck

Best

We just use ext@domainname it seems to be working fine here..
Works better than incoming calls from some sip providers here in oz actually.

Yes, on a quick test the phones are ringing but i had no audio, that is maybe a prob on the pc out of my lan.
