Call Sequence (Follow Me)

Call Sequence feature allows your extension to ring multiple numbers in order --- such as your desk phone first, then your mobile phone, then another extension --- until someone answers.

Sequential Ring is ideal for:

  • On-call workflows

  • Overflow to mobile

  • Multi-device ringing

  • Ensuring important calls never go unanswered

What Sequential Ring Does

When Call Sequence is enabled:

  1. Your desk phone rings first for the number of rings (or seconds) you specify.

  2. If unanswered, FS PBX rings your backup destinations one at a time in order.

  3. Ringing stops immediately when any destination answers.

  4. Optionally, "answer confirmation" ensures voicemail systems don't accidentally pick up.

How to Enable Sequential Ring

1. Open Your Extension Settings​

Navigate to:

Extensions → Edit → Call Forward (tab)

You will see several forwarding options:

  • Forward All Calls

  • When user is busy

  • When user does not answer the call

  • When Device Is Not Registered

  • Call Sequence (Follow Me) ← this is the Sequential Ring feature

Setting Up Call Sequence​

Scroll to the Call Sequence section:

Enable it using the toggle:

Call Sequence → ON

Step 1 --- Choose how long your devices ring first​

Example:

Ring my devices first for: 2 Rings (10s)

Step 2 --- Add backup destinations​

Use the "Add Backup Destinations or Contacts" input:

  • Enter a phone number

  • Or choose an internal contact

  • Or select multiple items in order

Click Add to Sequence.

Each entry has:

  • Delay --- how long to wait before ringing it

  • Ring for --- how long that destination is allowed to ring

  • Enable answer confirmation --- prevents external voicemail from answering

You can add as many steps as you need.

Presence Button (BLF Monitoring and Toggle from Your Phone)​

FS PBX includes a feature that lets users toggle the Call Sequence using a BLF key. Once the destinatons are set in the dashboard you can enable/disable the feture by pressing a button on your phone.

What the BLF shows​

  • LED ON: Call Sequence (Follow Me) = Enabled

  • LED OFF: Call Sequence = Disabled

  • Press the button: Toggles the feature instantly

Each tenant can have their own extension numbers (100, 200, 300, etc.) without conflict --- the BLF system is domain-aware.

Configuring the BLF Key​

On Yealink phones (and most SIP phones), add a BLF with:

Type: BLF
Value: fm$EXT
Label: FollowMe

Replace $EXT with the extension you want to monitor. Example - fm100 for extension 100.

This creates a SIP subscription to:

sip:fm100@yourdomain.com

FS PBX then sends real-time presence updates indicating whether Sequential Ring is enabled.
