Why this is useful
See how a preconfigured busy-lamp-field key can hand off an active call in one press. The short example is useful for reception staff who already have named extension keys and want to understand what happens when they select a colleague during a call.
Applicability
Version-specificAccelerate Networks GRP2615 key configuration. BLF subscriptions, transfer mode and lamp behavior depend on the phone template and PBX.
Keep in mind
- A green lamp is not a guarantee that someone will answer.
- Pressing a monitored key can behave differently when the target is ringing or when another transfer mode is configured.
Before you watch
Use a configured device and a willing test caller. Read the linked guide before changing settings.
Put it into practice
With two colleagues, try a handoff to an idle extension and confirm that the original caller reaches it. Learn your service’s busy and unanswered-call fallback before using a single-press transfer for live callers.
