Which is the VoIP gateway to get the best voice quality?
Is it Linksys/Grandstream/Audiocodes/..etc…?
I use the Linksys SPA2102-NA VoIP ATA (Analog Telephone adapter). There are three reasons I like this model.
1. It has a built-in Nat-Router.
2. It has built-in QOS, which gives VoIP priority over other local network traffic.
3. Select between high bandwidth (G.711u) and low-bandwidth Codecs (G.729a).
When its QOS is configured correctly, I find that the SPA2102-NA has very good voice quality. You will get best results when the ATA is directly connected to the Internet Modem and not after another Router between the Modem and the ATA.
I configure it with BYOD (bring your own device) VoIP carriers like CallCentric, Les.net, or InPhonex. CallCentric is currently my primary VoIP carrier and has very good voice quality with the Linksys SPA2102-NA ATA.
