Answer by Mr. VoIP
VoIP adapters like my Linksys SPA2102-NA do not seem to support SIP URI dialing. It supports IP dialing but not URI dialing such as yourname@yourprovider.com.

My SIP provider, CallCentric, does support SIP URI dialing through their network. I tested it with their Speed Dial feauture and successfully dialed my URI number at InPhonex. But, for it to work, I have to use their online Speed Dial feature through my web based Dashboard on CallCentric website.

But, my Linksys SPA2102-NA will not successfully send SIP URI’s through their service. I consulted with CallCentric support on this and they concluded the ATA does not actually support URI dialing.

The Linksys SPA2102-NA is a very good ATA and I like it quite well. However, it doesn’t seem to support URI dialing. As yet, I don’t know which ATA’s will successfully support URI dialing.
