Grandstream GRP2601 Series 2-Line Essential IP Phone — GRP2601, GRP2601P (PoE) & GRP2601W (Wi-Fi 6) | 2 SIP Accounts | 2.41-inch LCD | 5-Way Conference | EHS Support | GDMS Zero-Touch Provisioning | 1-Year Warranty

These phones suit small and mid-size offices, call centres, remote workers, schools, and service-provider deployments that need an affordable, reliable, easy-to-manage desk phone with strong security. Pick the GRP2601P where PoE switches are available, the GRP2601W where there’s no network cable at the desk, and the base GRP2601 where the phone is powered by its adapter.

Two SIP accounts and two lines cover a typical desk-phone workload, with 5-way audio conferencing, hold, transfer, forward, call park, call pickup, hotdesking, and flexible dial plans. The 2.41-inch 132 × 48 LCD, four XML-programmable softkeys, five navigation keys, and eight fixed keys (message with LED, transfer, headset, mute, send/redial, speakerphone, volume up and down) make operation straightforward. Noise-shield technology and AI noise reduction keep calls clear in noisy rooms, and an RJ9 headset jack with EHS support works with premium headsets. Wideband audio is supported (G.722, Opus), with G.729A/B, G.711µ/a-law, G.726, G.723.1, and iLBC also supported. Security includes secure boot, dual firmware images, encrypted data storage, TLS 1.3 with mutual certificate validation, SRTP (DTLS-SRTP and SDES-SRTP with AES-256), 802.1X, and SHA-256 authentication. Deployment is simple with GDMS cloud management, TR-069, or AES-encrypted XML provisioning for mass rollout, and the interface supports 26 languages. The phone has an XML or LDAP phonebook (up to 2000 contacts), an 800-record call log, click-to-dial through the GRP Click2Dial browser extension, and swappable custom faceplates. The base stand has a 45° angle and the phone is wall mountable (wall-mount bracket sold separately).
