Does voip work if I have poor internet reception?

Your internet has nothing to do with it. VoIP is is how you connect and talk on your local network

the CP-7821 is unable to setup. can you please tell me if its unlocked?

Hello Hossain, What call control system you're using to configure the phone? Make sure it is on of the following supported by the 7800 series phones: - Cisco Unified Communications Manager - Cisco Business Edition 6000 - Cisco Hosted Collaboration Solution - Cisco Unified Survivable Remote Site Telephony Thanks

do you have smartnet for this phone? price smartnet?

This phone is SMARTnet eligible but I do not have SMARTnet. I think it's $5-8 per phone for SMARTnet though.
