VoIP phone Grandstream (GRP2601) Review

Convenient and functional IP-phone of the basic level. This model provides the ability to connect 2 SIP accounts for voice communication using VoIP technology, the ability to convene and conduct a five-way audio conference. The Grandstream GRP2601P panel features 9 function keys for quick access to frequently required actions, as well as 4 XML programmable buttons. The design provides for the presence of 2 network adapters with a transfer rate of up to 100 Mbps. They support Power over Ethernet (PoE) technology. It is worth highlighting a number of other features of the device: 2.21-inch LCD display with image quality of 132x48 pixels. Suppression of background noise during a call. Opus and G.722 support. Enterprise-standard security with dual image, secure boot gateways, and encrypted database. Fast deployment and online management with GDMS support. Grandstream GRP2601P meets all modern IP telephony requirements. Everything you need is included in the package, but the power supply should be purchased separately, as it has been replaced by PoE.
