How to choose

Number of subscribers and channels. The capacity of an IP PBX determines the maximum number of simultaneous calls and registered accounts. For example, a platform for 200 SIP accounts is suitable for a medium enterprise, whereas a small office is served by a solution for 20-50 users.
IP phone class. The entry class comprises basic sets with 2-4 lines for rank-and-file employees. The mid and senior class implies a color display, more programmable keys, PoE support. For managers and operators, models with extended button-panel modules are suitable.
PoE support. Power over the Ethernet cable eliminates the need to run a separate 220 V cable to each phone, simplifies installation and reduces the cost of the installation.
Protocols and compatibility. Make sure that the phones and the PBX support SIP — an open standard ensuring compatibility of equipment from different manufacturers. The presence of TLS and SRTP support guarantees encryption of calls.
VoIP gateways for analog lines. If analog lines are already laid in the building or fax machines need to be connected, an FXS/FXO gateway is required, converting the analog signal into IP. Gateways with 72 or more ports cover the needs of large facilities.
