Questions about this item

Do the 24 paper-slot MPKs need any periodic replacement or cleaning?

The 24 multi-purpose keys use paper labels that can be swapped whenever extensions change; no electronic maintenance is required.

With dual switched 10/100/1000 Mbps ports, which link speed caps throughput during long calls?

Both ports autosense up to 1000 Mbps, so the Gigabit link is the practical ceiling for sustained traffic.

How much heat or fan noise does the GRP2636 produce when powered via PoE all day?

The phone has no fan and draws power through PoE, so it runs silently with only minimal warmth during continuous operation.
