Telephones and Systems.
We recommend and use Vonage for our business and residential phones. 

After trying numerous systems we recommend Vonage Business for small companies. We have phones in Indiana 5 locations in Colorado and 3 in Florida. This is a very flexible telephone system with features you and familiar with and some new ones. There is no big box on a wall somewhere that all the phones must connect to. All the phone are VOIP phones. They just plug into your internet router or switch. Once your phone is programmed you can take it anywhere in the world and it will ring. Vonage has super support 24/7 and the further great news is, that the price is right. Our phone bills went from $3,000.00 a month to less than 500.00.  We also have SIP lines for our Comrex VP Digital Stac Broadcast System.

This is the Comrex Digital VIP Stac Broadcast Telephone System that we use.
