Free phone with cool features. You don't even get this with your paid phone!!

PhoneAfter the Sun set at SunRocket I was phone less and got pissed off, I was searched on the web to see what other SunRocketians where doing and which service provider i should choose next.

After SunRocket demised with the money i paid i was reluctant to go for a prepaid annual plan and I decided to stick with month to month plan. After all research it was clear that none of the cheap VoIP providers were good. So i decided to hack my Linksys SPA2102-R and hook it up with a free VoIP provider. Sounds nice and easy, but find the solution for a free service isn't that easy.

SunRocketTo get the free phone line with cool features i had to use services from multiple providers and the list is

Enjoy your free phone

voipConnect your phone to Line 1 on your Linksys adapter and make sure the Linksys adapter is connected to Internet. It is recommended to connect this Linksys adapter to your cable/DSL modem directly instead of connecting it to a router or WiFi gateway. It should work with out any problem even if it is behind a router as we have enabled STUN

From your mobile phone or from a different phone call your GrandCentral number this should ring your VoIP phone Cool After you pick up the call answer it after pressing 1 and start to talk.

Grand Central doesn't want to land on your phone's voice mail so all the calls has to be answer after pressing 1. I wish my VoIP adapter can send a DTMF 1 as soon as i pick up the phone Innocent
