Goals
- Align BLF and Extension behavior for PFKs on Snom desk phones by using XML definitions instead
- Improve user experience
- Improve performance
Background and strategic fit
BLF is a valuable feature for Snom customers, like enterprises who are looking to assist in connecting their customers to a live, available person as well as save business phone use time. Overall, it enables businesses to streamline their communication and better serve customers.
Assumptions
- BLF aka Extension monitoring has been utilized in numerous ways by businesses using Snom phone systems with multiple extensions. The current implementation appears to be kind of duplicated, but with a few little differences and erroneous behaviour.
- Use case#1: A secretary's phone shall display the call status of the boss's line, allowing the secretary to know whether the boss is on a phone call or not. This will enable the secretary to make the decision to put the new caller on hold or let them through to the boss.
- Use case#2: Call centers and customer support groups have also a need for BLF: it enables employees to see if their colleagues are free to take a support call or if their supervisor is on another line and unable to help another customer.
- Use case#3: BLF is needed by teams working on a specific project: supervisors can monitor team members' extensions and vice versa so all team members are aware of each other's current status.
Requirements
| # | Title | Functional | Importance | Notes |
|---|---|---|---|---|
| 1 | BLF-XML-01-00 | On D8xx, any PFK (physical or virtual programmable function key) can be assigned to the function BLF. |
| |
| 2 | BLF-XML-01-01 | The assignment shall be configured either manually via web user interface (WUI) and/or phone user interface (PUI), and automatically via auto-provisioning (HTTP/TFTP setting server), SRAPS, or remote management (TR-069). | ||
| 3 | BLF-XML-01-02 | If such SIP extension is configured on other Snom phones in the same SIP domain BLF shall work transparantly without the need of an IP PBX. | ||
| 4 | On D8xx, during an active subscription, state changes of the monitored SIP extension shall be visualized on both, PFK LED and PFK icon & label. | |||
| 5 | In case the notifier being an IP-PBX or another Snom phone: Idle state => PFK LED off, PFK label & icon "idle" | |||
| 6 | In case the notifier being an IP-PBX or another Snom phone: Ringing state => PFK LED blinking fast (colour?), PFK label & icon "ringing" | |||
| 7 | In case the notifier being an IP-PBX or another Snom phone: Busy state => PFK LED on (colour?), PFK label & icon "on a call" | |||
