Notes:
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. Some numbers such as Vonage numbers can only be called for free from other Vonage phones, so Vonage is NOT open to calls from other SIP proxies.
