To enable Caller ID popup screens within your application you will need to determine which hardware integrates with your system. Hardware is a one-time purchase; we charge no recurring license fees of any kind.

We offer analog Whozz Calling? devices (Basic or Deluxe) or the Vertex product for VoIP service. Once it is determined the exact unit needed, you can find your cost on the End Users Pricing page.

Look up the model number of the phones you are using to determine whether an analog or VoIP device is required.

You use "off-the-shelf" phones

If the phones can be purchased from any local retailer, then an analog Whozz Calling? unit is required. Standard phone cords connect wired analog phones and analog wireless base sets.

Most Software companies have integrated either Whozz Calling? Basic or Deluxe units which are connected either via Serial Port or Ethernet. Some have written their application for multiple type units.

Determine the appropriate Whozz Calling? hardware to purchase using the Product Selection Guide.

You use VoIP phones

Instead of a phone cord, wired VoIP phones are connected with an Ethernet cable. Wireless VoIP phones use a base set connected with an Ethernet cable. If using VoIP phones, then the installation requires the Vertex Vertex product.

Popular VoIP Phone Brands
  • Cisco
  • Polycom
  • Yealink
  • Grandstream
  • Mitel (not compatible)

The Vertex unit is compatible with any software that has integrated into CallerID.com hardware.

You use an on-site phone switch

If your phones are extensions off a phone system switch, then it needs to be determined what type of external phone lines are feeding the switch.

Popular Phone Switches
  • Avaya
  • NEC
  • Nortel
  • Panasonic
  • Toshiba
  • Mitel
  • Vodavi
  • AT&T Merlin
  • Comdial
  • If analog phone lines are feeding the phone switch (direct from the provider, cable box or other analog converter, see below) then an analog Whozz Calling? unit is required. Use our Product Selection Guide to determine the appropriate Whozz Calling? hardware needed.

  • If there is a SIP trunk (VoIP) connection to the phone switch then a Vertex "CallerID for VoIP device" is required.

  • If an ISDN-PRI feed is present, then CallerID.com has no hardware solution.

You have "Digital" or "VoIP" service

If you know only that your service is "Digital" or "VoIP" that may not be enough information to select the appropriate equipment. You may have an on-site device such as a cable modem or other equipment that converts the incoming signaling to analog lines. Checking the phones model is always the most prudent method of determining whether analog or VoIP Caller ID equipment is required.
