Not verifying these three things could affect call quality when using cloud VoIP service

You just started using your new Cloud VoIP phones and the sound quality is awful. So now what do you do? 

Questions you should consider if the IP phones and service you ordered from the Internet sound awful. 

 Do you have enough bandwidth? (VoIP service uses your Internet connection and low bandwidth can cause problems)
 Do you have an additional data switches installed between the main data switch and the IP phone (Not recommended)
 Are you using inexpensive routers and switches? (Cheap routers and switches are the most common reason for poor call quality)
 Is your cabling infrastructure category 5 or higher? (Plan on re-cabling, if it's not)
 Is the phone sharing the same data jack as the computer? (You may have to run separate cabling connected to separate routers and switches, which will almost guarantee a major improvement and call quality)

You'll never improve the call quality if you don't know the answers.
Verify that your existing cabling will support IP phones
Verify existing switches and Routers will support IP Phones
 Verify you have adequate bandwidth to support IP Phones

You can invest in the most expensive stereo speakers on the market, but they probably will sound lousy with a cheap amplifier and cable. It's the same analogy for voice over IP service. Don't assume anything!  Make sure your service provider does a free on-site survey before signing any contract.
