Yealink Multicast Paging - T43U

[andrew.k]

Hi all,


I'm deploying multicast paging on Yealink T43U phones using 3CX, and I’ve run into a problem that I can’t seem to resolve.

---

The Situation​

• If I manually configure multicast paging through the Yealink Web UI, everything works perfectly:
  
  
  
  
  
  
  
  • The phones send and receive multicast pages
  • Paging functions persist and behave correctly
• But this approach requires me to manually configure every phone, and of course:
  
  • On reboot or factory reset, the phones lose all multicast settings
  • This isn’t sustainable across a large deployment
    
    
    

  • The Problem​

    
    When I take the exact same working multicast paging settings and hardcode them into the 3CX provisioning template, the phone provisions successfully, but multicast paging no longer works.
    
    
    

    Why does manually entering multicast settings through the Web UI work, but provisioning those same values via template fails ?

    
    Here’s what I’m hardcoding in the template:
    
    
    
  • # Multicast Paging Configuration
    features.multicast_enable = 1
    features.accept_paging.enable = 1
    features.send_paging.enable = 1
    multicast.codec = G711U
    multicast.receive_priority.enable = 1
    multicast.receive_priority.priority = 10
    multicast.listen_address.1.label = Paging Group
    multicast.listen_address.1.ip_address = 224.0.0.100:6000
    multicast.listen_address.1.channel = 1
    multicast.receive.ignore_dnd.priority = 0
    multicast.receive.use_speaker = 1
    
    I also configure the line key as follows:
    
    
  • linekey.1.extension = 1
    linekey.1.label = Paging Group
    linekey.1.line = 1
    linekey.1.type = 24
    linekey.1.value = 224.0.0.100:6000
    
    
    here is the 3cx config for the multicast :
    

Any help or insight would be much appreciated.

Thanks in advance,

If it helps, here is a sample of a template I have used for multicast on Yealink T42G/T46G/T48G. It reassigns a key on the bottom row of the display to show the paging group list. Assuming the same codes apply to the T43U, I think you may need to fix the codec assignment.

multicast.codec = PCMU
multicast.receive_priority.enable = 0
multicast.receive_priority.priority = 0
multicast.paging_address.1.ip_address = 239.0.0.1:1001
multicast.paging_address.2.ip_address = 239.0.0.1:1002
multicast.paging_address.3.ip_address = 239.0.0.1:1003
multicast.paging_address.4.ip_address = 239.0.0.1:1004
multicast.paging_address.1.label = Page All
multicast.paging_address.2.label = Zone 1
multicast.paging_address.3.label = Zone 2
multicast.paging_address.4.label = Zone 3
programablekey.3.type = 66
# programablekey.3.value =
# programablekey.3.label =
# Multicast listeners (uncomment to apply zone assignment)
multicast.listen_address.1.ip_address = 239.0.0.1:1001
multicast.listen_address.1.label = Page All
multicast.listen_address.2.ip_address = 239.0.0.1:1002
multicast.listen_address.2.label = Zone 1
# multicast.listen_address.3.ip_address = 239.0.0.1:1003
# multicast.listen_address.3.label = Zone 2
# multicast.listen_address.4.ip_address = 239.0.0.1:1004
# multicast.listen_address.4.label = Zone 3
