Insights

For organisations with demanding VoIP requirements, a basic IP phone may not provide enough lines, extension monitoring, or connectivity options. The Grandstream GRP2615 is designed for users who need to manage a high volume of business communication from a single desktop endpoint.

With 10 line keys and up to 16 SIP accounts, the GRP2615 provides flexibility for users who manage multiple extensions, SIP services, or business communication accounts. Each SIP account can have independent SIP server, user, and NAT settings, allowing the phone to support more complex communication environments.

The phone is particularly useful for receptionists, managers, call-handling staff, and other users who need to monitor multiple colleagues or extensions. Its 40 digital BLF/fast-dial keys provide quick visibility and access to monitored extensions, while an optional GBX20 extension module can add another 40 BLF/speed-dial keys per module.

Connectivity is another major advantage. The GRP2615 includes dual Gigabit Ethernet ports with integrated PoE, along with integrated Wi-Fi and Bluetooth. This allows organisations to select the most suitable connectivity method for each workstation while maintaining a professional and flexible deployment.

For larger deployments, GDMS provides a centralised platform for configuring, provisioning, monitoring, and managing compatible Grandstream endpoints. This can help reduce the administrative effort involved in deploying and maintaining large numbers of IP phones.
