Internet Phone, Everfree/p2p

 
 
 

EverFree/p2p is a PC-based internet phone, and makes services without any support of service provider. Most of the existing internet phone services make phone calls available with the support of internet phone service companies, and have the disadvantage that users have to pay registration fee and monthly usage fee or fixed monthly charge. Also, due to severe competition, some companies are withdrawing from the market, in which case, equipments like terminals that users purchased for high price in the beginning become useless and there is no guarantee that users can get repaid their registration fee.

However, the initial purchase cost of EverFree/p2p is lower than other similar products. Once equipments are purchased, users need not expend additional costs. Also, since there are not many occasions users have to rely on the manufacturer, users can use it without worrying about manufacturer's bankrupt. EverFree/p2p users who are on a trip abroad may be free from telephone fee, because it is possible to make calls between EverFree/p2p and any PC in the world. It is very convenient to dial with remote dialing, two.

IP Environment

There are pseudo internets which can not support all internet protocols. Those pseudo internets mostly use private IP in both sides, or sometimes use public IP with limited functions.
In operating EverFree/p2p, IP plays a very important role and EverFree/p2p might not operate properly depending on combinations of IPs. EverFree/p2p operates well in all the regular internets. Because EverFree/p2p might not operate properly in case of pseudo internet, it is recommended to use regular internets when users use EverFree/p2p.
