Business Telephones: Desk, DECT and IP Phones

Lines, handsets and who answers the phone

Business use starts with how many calls arrive at once. A single-line phone handles one; models listed as 'up to 4 lines' let several calls wait or be taken by different people. DECT systems pair a base with wireless handsets so staff can move around, and some DECT listings state ten lines. IP models with PoE and a color screen sit on the office network. Decide whether staff stay at desks, then choose corded, DECT or IP accordingly.

Complete phone, add-on handset or accessory?

This category mixes complete phones with parts. A listing typed 'handset' may be an add-on that needs a compatible base, a wall bracket fits only the phone models it names, and some titles describe a conference phone with wireless microphones. Look at the product type and the handset count to see whether a base is included. Handsets with a built-in lithium-ion battery still need a charging cradle or cable, and the pack is not always user-replaceable, so check how it is serviced.

Questions about Business Telephones: Desk, DECT and IP Phones

How many phone lines does a small office need?

Count how many calls can happen at the same time in your busiest hour and choose that many lines. On IP systems the lines are software accounts shared among phones, so the key layout on the phone matters more than the wiring.

Can a DECT business phone connect to an IP phone system?

Only if the base supports SIP or the line type your system uses. Some DECT bases connect to an analog line, others to an IP network, and the listing's line type and protocol tell you which.

Does a built-in battery mean no charger is needed?

No, it still needs charging, usually in a cradle or by cable. Check whether the battery is replaceable, because a sealed lithium-ion pack can end the useful life of the handset when it wears out.
