* Unlocked PAP2 + Router with QoS adapter works with any SIP voip provider of your choice, such as Babytel, Acanac, StanaPhone, Vbuzzer, Gizmo, Voipbuster, Voipstunt, etc. It has 2 separate phone lines. You can configure 2 independent phone numbers at the same time, one for North America, another for oversea.
* PAP2 + Router with QoS is better then just PAP2, because they already have a good router built inside with many features including QoS, which makes voice quality better. Not every router has QoS feature. Therefore, this device is better than a combination of just a PAP2 and a regular router without the function of QoS.
* Plus, PAP2 adapter, for some reasons, doesn't work well with every router in the market. Sme people changed their router just because it didn't work with PAP2. When you have a PAP2 + Router with QoS adapter, you won't have that risk. It is plug-and-play. That's why PAP2 + Router with QoS is better then just PAP2.
* What is QoS? It is short form of Quality of Service. It gives priority to voice signals in your networking. Let's say you're using internet for download, when you receive or place a call, the router slows down all your jobs and prioritizes on voice signals. That helps receiving better voice quality.
