VoIP is comparatively new concept in Pakistan, and thus is hot now a day. Almost everyone is talking about it. The reason for so much attention is nothing, but the advantages it’s bringing. For instance, transmitting more than one telephone call over the same broadband connection to add an extra telephone line, conference calling, call forwarding, automatic redial, and caller ID etc, that’s charged by telecom companies normally, is all within it’s package.
Other than this, the only thing required for VoIP is the internet connection, and you can have video conferencing, even. Since it’s an emerging concept here at our end, so things are not like developing countries, where there are many security issues related to VoIP. There’s a competition as well, you can see some VoIP reviews here. After cellular revolution, I think, we’ll soon be going to have VoIP revolution as well.
