connecting two ip phones

[Bertram]

For the experts on this forum this might be a too easy question:

I would like two connect two cisco spa 301 ip phones with one cisco sg300 switch between both. Just to be able to make phone calls from one ip phone to the other, nothing else. Which sip programm should I use and how do I have to configure this?

Many thanks in advance

You need a registrar server to register these phones in the first place before you can make calls.

Thank you for you response. Meanwhile I found the solution:

Both Ip Phones with static ip adress
Proxy and registration put in proxy the ip number from the opposite phone

Dial plan (So<ip number of destination)

Thats it

So did this work?
