W60B/W70 - Individual Line Ringing

Incoming Lines

handset.1.incoming_lines="1"
handset.2.incoming_lines="1"
handset.3.incoming_lines="1"
 

Dial Out

handset.X.dial_out_default_line="1,2,3,4"

handset.X.dial_out_lines="1,2,3,4"

EXAMPLE: 

Assume there are 3 handsets assigned to 3 different extensions:

  • Line Key 1 = Macky's extension
  • Line Key 2 = Sean's extension
  • Line Key 3 = TJ's extension

To configure the following overrides on the base:

handset.1.incoming_lines="1"
handset.2.incoming_lines="2"
handset.3.incoming_lines="3"

handset.1.dial_out_default_line="1"
handset.2.dial_out_default_line="2"
handset.3.dial_out_default_line="3"

Then, if all three users need the ability to place outbound calls using any of the available line keys, use these:

handset.1.dial_out_lines="1,2,3,4"
handset.2.dial_out_lines="1,2,3,4"
handset.3.dial_out_lines="1,2,3,4"

Multicast Paging

Listen

This override allows a device to receive multicast pages from other devices.

multicast.listen_address.X.ip_address="ip address"
multicast.listen_address.X.label="Page All"

EXAMPLE: 

multicast.listen_address.1.ip_address="239.0.0.4:10004"
multicast.listen_address.1.label="Page All"
multicast.receive_priority.priority="0"

 

TIP:

  • listen_address.X – Identifies the multicast listening entry on the phone.
  • ip_address – Must match the sender’s multicast IP address and port.
  • label – Specifies the name displayed for the listening group.
  • receive_priority – Controls how an incoming page behaves when the phone is already on a call. Use the priority value that best meets the customer’s paging requirements.
    • Priority 0 – The page does not interrupt an active call.
    • Priority 1 – The page may interrupt an active call.
 

 

Broadcast

This override allows a device to send multicast pages to other devices.

linekey.X.type="24"
linekey.X.value="235.0.0.1:10001"
linekey.X.label="Page All"

EXAMPLE: This example creates a Page All button on line key 12.

linekey.12.type="24"
linekey.12.value="239.0.0.4:10004"
linekey.12.label="Page All"

 

TIP: 

  • linekey.X – Identifies the physical or virtual line key used for the paging button.
  • type=“24” – Assigns the multicast paging feature to the line key.
  • value – Specifies the multicast IP address and port used for paging.
  • label – Specifies the name displayed on the phone.
 

 

Paging from Yealink to All Polycom Phones (Default Paging Group)

This override allows a Yealink phone to send multicast pages to Polycom phones using the default Polycom multicast IP address and port.

linekey.12.type="24"
linekey.12.value="224.0.1.116:5001"
linekey.12.label="Page All"
linekey.12.extension="1"

TIP: 

  • linekey.12 – Identifies the line key used for the paging button.
  • type=“24” – Assigns the multicast paging feature to the line key.
  • value – Specifies the default Polycom multicast IP address and port.
  • label – Specifies the name displayed on the phone.
  • extension - Should equal the page group number
    • E.g., For Page All, extension="1". If the 2nd page group is Sales, the extension should be extension="2".
 

NOTE: 

  • Polycom phones must be subscribed to the appropriate paging group to receive multicast pages.
  • 224.0.1.116:5001 is the default multicast IP address and port used by Polycom phones.
  • If the Polycom multicast IP address or port has been customized using ptt.address or ptt.port, update linekey.12.value to match.
  • The Yealink and Polycom must use the same multicast IP address and port for paging to function correctly.
  • Both devices must be on the same network, or multicast routing must be configured between networks.
 

 

Paging from Yealink to Polycom

This override allows a Yealink phone to send multicast pages to Polycom phones.

Yealink (Sender)

linekey.X.type="24"
linekey.X.value="224.0.1.116:5001"
linekey.X.label="<Insert Page Group Name>"
 

Polycom (Receiver)

TIP: 

  • linekey.X – Identifies the physical or virtual line key used for the paging button.
  • type=“24” – Assigns the multicast paging feature to the line key.

Polycom

  • ptt.pageMode.group.X.subscribed=“1” – Subscribes the Polycom phone to the specified paging group.
  • Replace X with the desired Polycom paging group number.
 

NOTE: 

  • The Yealink sends multicast pages to a multicast IP address and port. It does not specify a Polycom paging group.
  • The Polycom phone must be subscribed to the desired paging group to receive multicast pages.
  • 224.0.1.116:5001 is the default multicast IP address and port used by Polycom phones.
  • If the Polycom multicast IP address or port has been customized using ptt.address or ptt.port, update linekey.X.value to match.
  • The Yealink and Polycom must use the same multicast IP address and port for paging to function correctly.
