How to use

Connect the GRP2602G to your IP network and power it via the supported method for this model (refer to your variant for PoE or external power). Use GDMS or the phone’s web interface to provision SIP accounts and apply configuration templates. Place calls using the handset, speakerphone or a compatible EHS headset; use the on-screen menu to access call features, conferencing and audio settings. For bulk deployments, enable zero-touch provisioning so devices automatically fetch configuration from your provisioning server at first boot.

Recommendations

For secure operation in enterprise or provider networks, ensure GDMS is used for centralized provisioning and firmware management, keep firmware updated, and configure encrypted transport (TLS/SRTP) for SIP signaling and media where supported.
