You can call the following VoIP numbers for free. From a softphone, just copy&paste the full SIP address (sip:user@domain.com).
From a hardware SIP adapter, copy&paste the full SIP address into your speed dial web page. All of these numbers worked in April 2009.
Please list only *open* VoIP phone numbers and Free VoIP Networks, meaning that you have successfully made a call to that number from a SIP proxy located in a different domain. On the other hand, Vonage numbers can only be called for free from other Vonage phones, so Vonage is NOT open to calls from other SIP proxies.
