What is the best hardware combination (router, modem, voip adapter)?
I have adsl modem. I find when I add voip adapter there's a hardware conflict. Is it a port forwarding issue? Or is it a hardware? And if it's hardware what's the best combination of product to avoid technical glitches?
The best solution I have found is to put my Linksys SPA2102-NA VoIP ATA directly behind my cable modem. The SPA 2102-NA has built-in Router and QOS and gives all VoIP traffic priority over all other data.
Then, I have my Linksys WRT-54G after the SPA2102-NA. Then, my PC is connected to the WRT-54G. I have VoIP Softphones on the PC that are working just fine this way. The WRT-54G does have to Port Forward SIP Ports 5060-5061 (UDP) and RTP ports 10,000-20,000.
Previously, I had the Linksys WRT-54G NAT-Router directly behind the Modem. And the WRT-54G was port forwarding VoIP SIP ports 5060-5063 (UDP) and RTP ports 16,384-16,482. Then, my Linksys PAP2T-NA VoIP adapters and PC were connected to the output ports of the WRT-54G.
I'm finding that I have better results with the Linksis SPA2102-NA directly behind the Modem. Then, everything else after that. I am getting very good VoIP quality with my VoIP carriers this way.
I highly recommend the Linksys SPA2102-NA adapter configured with your own BYOD VoIP provider of choice.
