Itel Office for PSTN - Screenpop by CallerID

Get your computer to do all the work and find the calling contact for you via our Itel Office screenpop by caller ID technology. If this contact has called before, then all the information can be at your fingertips. If the caller hasn't called before, then Itel Office will help you add it to your address book.

Itel Office for PSTN currently supports two PSTN Caller ID devices: Comet CTI USB Caller ID and Whozz Calling? Basic POS. The Comet device can be used on the UK public switched telephone network, PSTN. The Whozz Calling? device is supported in a wide range of countries. These devices allow Itel Office to screenpop the caller based on their caller ID.
