Xlite has good features with SIP Protocol, such as recording, conferencing, etc.,

Register http://www.sipphone.com and connect to their service with the two softphones.

Phone to GSM Gateway VoIP Routing - Part 1

It is been request from my friends how to connect Normal phone Number to a GSM Gateway connected remotely in a different country.

This article gives a brush up how to use the SIP Protocol to make VoIP Calls and communicate freely in the internet.

Visit few of the public service providers:

1. http://www.sipphone.com
2. http://www.iptel.org/toboggan/login
3. http://www.sipgate.com/

I find these ones are reliable with their service.

If you would like to have your own server at home. You can use the following softwares as sip proxy.

1. Asterisk
2. openser
3. freeswitch

I would recommend Asterisk, since it is used by large users and enterprise and proven to be stable. It can also even run in routers and embedded devices too.

Try to get the accounts setup or install the softwares in a Linux Machine, Before we go to the next step. I would be choosing, sipphone & Asterisk in my forthcoming examples and configurations.
