Direct call to IP address

Hi, I don't know how to call computers by ip... if you use any software like x-lite it listens always on a specific port you set somewhere in the settings menu.
unfortunately I don't know how to call ips on a specific port and you use port forwarding only when nat is enabled.

Calling ip phones directly (without nat) works perfectly. I already tried.
you simply type in the ip and instead of the dots you use *

Hi All,

Because there is no English forum for the S450 IP, I'll post my question here. Hopefully that is not a problem!

that's true, but I found on siemens' french website an english speaking blog.
just search here for the following topic

fyi: Siemens-Blog für S450IP

it is written in german but in short: I wrote that there is something in english and the french guys also have some issues concerning the s450 IP

When I want to call an IP address directly, what is necessary at the receiving computer ?
I assume I need to have some program running that receives the call. Could e.g. the VoipBuster software be used for that purpose ?
What about when the receiving computer is in a local network? Do I need to have portforwarding enabled ? What port is used ?
Any other issue I should take care of?

Thanks,
Jan
