The power supply is important for ensuring that the phone can operate continuously without interruption. Some phones come with PoE (Power over Ethernet) support, while others require an external power adapter. For example, the Yealink SIP-T48U supports PoE, and the Polycom VVX 250 comes with an AC power supply. Various models are available with different power supply options to suit different installation scenarios.
