Intercom/Paging

 

The Paging and Intercom features allow you to make an announcement to a group of extensions. The called parties do not need to pick up the handset, as the audio will be played via the phone’s speakers.

 

Set up 1-Way Paging

Paging is used to make an announcement over the speakerphone to a phone or group of phones. The called parties will not ring, but instead answer immediately into speakerphone mode.

About this task

Note: Paging is typically one way for announcements only.

Procedure

  1. Go to Settings > PBX > Call Features > Paging/Intercom, click Add.
  2. Set a 1-Way paging group.

Set up 1-Way Multicast Paging

Multicast Paging allows you to easily and quickly broadcast instant audio announcements to phone users who are listening to the same multicast IP address of the PBX.

About this task

When you make a Multicast Paging, the PBX sends Real-time Transport Protocol (RTP) streams to the IP phones without involving SIP signaling. The phones that will receive the RTP streams don’t need to register SIP extensions.

Note:

  • The IP phone that will receive 1-way multicast paging should support Multicast Paging feature.
  • The Multicast Paging is one-way audio call.

Procedure

  1. Set a 1-way Multicast Paging on the PBX.
    1. Go to Settings > PBX > Call Features > Paging/Intercom, click Add.
    2. Set a 1-Way multicast paging.
      Intercom & Paging 3
      • Number: Use the default or specify an number for the paging group.
      • Name: Enter a name for the paging group.
      • Type: Choose 1-Way Multicast Paging.
      • IP of Multicast Channel: Enter the multicast IP address and port (e.g. 224.255.255.255:1000).
        Note: The range of multicast IP address is 224.0.0.0 – 239.255.255.255.
    3. Click Save and Apply.
  2. Set Multicast Paging on each of your IP phone.
    In the following, we take Yealink T27G as an example.
    1. Log in the phone web interface, go to Directory > Multicast IP.
    2. In the Multicast Listening section, enter the same multicast IP address and port of the PBX.

    3. Click Confirm.

Results

When you dial the paging group number, the members in the group will automatically answer the call into speakerphone mode.

Note: If the multicast paging doesn’t work, check the following:

  • Multicast IP address and port are in the correct range.
  • If the PBX and IP phones are in different IP segments (e.g. PBX is in 192.168.5.X IP segment, IP phones are in 192.168.3.X IP segment), check if your router supports IP Multicast in different IP segments.

Make an Announcement to a Specific User

Extension users can dial the intercom feature code to make an intercom to a specific extension, the called party can respond immediately without picking up the handset.

About this task

The default Intercom feature code is *5.

Note: In this way, the audio is two way, both the caller and called party can hear each other.

Example

Extension user 2000 makes an intercom call to extension user 1000.

  • Dial *51000 on the phone of extension 2000.

    The call on extension 1000 will be answered automatically.
