If you need speed dials, busy lamp fields, or line keys programmed into your phone’s switchboard and/or sidecar unit fill out the spreadsheet and submit it through our Support Portal.

This article covers the following topics:

Supported Devices

Currently we are supporting Line Keys configuration on these phones:

  • Polycom VVX 300/310/400/410/500/600
  • Cisco SPA303/SPA504G/SPA525G2
  • Yealink T40P/T41P/T42G/T46G/T48G

Also it is possible to assign functions to Line Keys on these devices:

  • Polycom VVX Color Expansion Modules
  • Cisco SPA500DS (Applies only to SPA502G /SPA525G2)
  • Yealink Expansion Modules

Important: Yealink T42S/T46S/T48S phones will not pertain the Line Keys changes made on the back-end. Line Keys would need to be manually configured in the WebUI of these phones.

Introduction to BLF sheet

With few exceptions, our Hosted PBX 2.0 generally supports only the following key types: 

  • Line Key
  • BLF
  • Speed Dial

 There is a sample below:

If it has a sidecar attachment, put additional requests in this section below:

In the case where you have multiple phones of the same manufacturer, employ the sheet copying method as follows in the Diagram:

Once copies are created, name the sheets to represent which extension's BLF/speed dials are being configured. This will represent a completed BLF request sheet.

The end product looks like this:

Key types

Line key

This is the phone's own line, and is used to indicate ongoing (active, held and ringing) calls, as well as to initiate outgoing calls. If there are multiple Line keys set up, ongoing calls will be spread over them and can be switched to with a single key press, putting the currently active call on hold.

Also, you can initiate a new call and put the current call on hold with a single key press, via an unoccupied Line key.

Busy Lamp Field (BLF)

This is a flexible multifunction key that depends on its current state. Its primary function is to monitor another phone (defined by its extension) -- it cannot interact with non-phone extensions like park groups, paging groups, etc.

If the monitored extension is ringing, using this button activates the Directed Call Pickup, i.e., intercepts the call incoming on that extension (even if the call in question is via a hunt group and rings both the monitored phone and yours). Otherwise, it works as a speed dial for that extension.

Speed dial

This is the key set up to dial the programmed number/extension/code sequence. This is the option that can be used to dial the park group.

To use speed dial with park groups, usually, we program one key as Park (code 9000) on phones which might need to park the call, and program one or more keys as Park 1, Park 2, etc. (code 9001 for first call, 9002 for second, and up to 9004) on phones which might need to retrieve it.

This requires the person who will need to retrieve the call to know a call is parked and which park extension to use to retrieve it though.

Voice Mailbox forwarding

Another thing speed dial is sometimes used for is to set some keys for reaching a specific voice mailbox which is generally done by prefixing it with *99 (i.e. to reach extension 102’s voicemail, it should have *99102 coded in).


Huntgroup incompatibility

Note: that in case of a mesh (each phone in a group monitoring each other phone) BLF, any simultaneous hunt group call will cause the BLF keys to fire up as well.

Additionally, it is not generally recommended to have busy lamp functions set up for phones which are contained within 1 or more hunt groups. You can check this by looking at the auto attendants on yourHostPilot login, making sure the phone you want to install BLF/SD on is not already in a hunt group container. This has a habit of oversaturating the phone call, or session, with too many commands to carry through. Note that this can cause calls to drop unexpectedly.

Turnaround time

Our standard quote on turnaround time for these requests is 2 business days. This will depend on volume, and may even sometimes be done sooner. In case there are any edits you want to add in, after having submitted the form, it is best to resubmit the form with the updated requests overlaying the existing request being worked on, rather than just saying “add an additional speed dial” in an email to our Voice support team.

These requests are handled by our backend Voice engineers and do take time to be completed. Please be sure and keep the local copy of your spreadsheet in case it is lost.
