ATA adaptor - Analog Telephone Adapter is a device that connects traditional analog telephones and fax machines to a VoIP network.
 You may want to buy one if you have some standard telephony equipment that works well for what it does but you want to use with your VoIP network.  In other words, ATA allows you to avoid having to operate and maintain two networks (standard and VoIP), keeping equipment that is functional without requiring the advantaged of VoIP.

Cordless SIP phones (that work with a VoIP network) offer the convenience of being able to step away from your office desk. They are a good choice for people who prefer talking into a hanset over using wireless headphones. 


Cordless phones can plug directly into a computer, a setp up in which only one user can use them. But to really expand on their usability they should be plugged into a network or using a base station, allowing for multiple accounts and handsets to be used (extra handsets need to be bought separately). 


Notice in the comparison table that in addition to the number of handsets a phone supports, there is also a feature of different phone numbers. In most cases you would want a separate phone number for every handset, but there is also an option to share numbers among several workers.
