Linksys Internet Phone Adapter with 2 Ports for Voice-over-IP PAP2T Review

I've been using my unlocked Linksys Internet phone adapter PAP2T for about a year now with my SIP service provider and I thought that I would write my thoughts on it.

Configuring the device was fairly simple. It involved connecting the device to my router and the power supply as well as connecting an analogue telephone to the PAP2 Line 1 port. After waiting approximately 60 seconds, you would pick up the phone receiver and then hit the "*" key on the phone 4 times. You will then hear a message about the configuration menu. Press "110#" and the system will then reply with the IP address for the device.

Using your web browser connected to the same network as the newly plugged in Linksys Internet Phone Adapter, you basically only have to plug in the IP address into the browser's address bar and it will go into the configuration screen for the device.

Depending on your SIP provider, you will have to make the changes in the configuration screen for the Linksys Internet Phone Adapter.

I use VoIP.ms and I found the configuring the Linksys Internet Phone Adapter for VoIP.ms to be pretty straightforward (comparable with configuring SIP clients on my smartphone). Yes, the Linksys Internet Phone adapter has a lot more parameters than the standard SIP client on a smartphone but all I did was configure the parameters that were required.

VoIP.ms actually has a configuration document specifically for the Linksys Internet Phone Adapter PAP2T. I created a PDF (printed to PDF) from the wiki created by VoIP.ms.

I configured each telephone RJ-11 port to work with a different account with different phone numbers.

In terms of the quality of service, like with all VoIP solutions, the sound quality will depend a lot on the speed/bandwidth/latency of the internet connection that it is plugged into. I would say that the sound quality is better than what I am getting with my SIP client on my cellphone configured to use the same wireless router/network because the Linksys Internet Phone Adapter uses a network cable and doesn't connect to a wireless network which is generally less stable than a wired connection. The Linksys Internet Phone Adapter also had the added benefit of using a real phone which I find has better sound quality than most cellphones.

If you are subscribed to a SIP provider, I have no problems recommending the Linksys Internet Phone Adapter (as long as you purchase it unlocked since some Linksys Internet Phone Adapters are locked to a particular SIP provider or SIP carrier). It works very well and set-up is relatively simple.
