The multicast function enables the initiator to send voice messages to a specified multicast address. All phones listening to the specified multicast address can receive voice messages from the initiator. The function is similar to broadcasting. Using the multicast function, you can easily send announcements to each member of the multicast group.
Operating mechanism
The IP phone uses the WEB UI to configure multicast address,port and code.Set the listening multicast address and port on the WEB UI.
The phone initiates a multicast,and all phones listening to the IP address can receive the multicast content.
description
In broadcast multicast, the phones that use multicast must reside on the same network segment. The IP phone can only send or receive broadcasts on the same channel, and roadcasts on other channels are ignored.
Parameter | DBID_MULTICAST_PAGING_BARGE_PRIORITY |
---|---|
Description | It configures the priority of the voice call (a normal phone call rather than a multicast paging call) in progress. 1 is the highest priority, 31 is the lowest priority. |
Permitted Values | 0-Disable, all incoming multicast paging calls will be automatically ignored when a voice call is in progress. 1-1 2-2 3-3 … 31-31 If it is set to other values, the phone will receive the incoming multicast paging call with a higher or equal priority and ignore the one with a lower priority when a voice call is in progress. |
Default | 31 |

Parameter | DBID_MULTICAST_IGNORE_DND_PRIORITY |
---|---|
Description | It configures the lowest priority of the multicast paging call that can be received when DND is activated in phone mode. 1 is the highest priority, 31 is the lowest priority. |
Permitted Values | 0-Disable, all incoming multicast paging calls will be automatically ignored when DND is activated in phone mode. 1-1 2-2 3-3 … 31-31 If it is not set to 0 (Disabled), the phone will receive the incoming multicast paging call with a higher or same priority than this value and ignore that with a lower priority than this value when DND is activated in phone mode. |
Default | 0 |
Web UI | Phone > Multicast IP > Multicast Listening > Ignore DND |
Parameter | |
---|---|
Description | It enable or disable the Paging priority feature. If it is enabled,the phone automatically ignores the multicast RTP stream with a lower priority, receives the multicast RTP stream with a higher or equal priority, and puts the current multicast session in the hold state. If it is diaabled,the IP phone automatically ignores all received multicast RTP streams. |
Permitted Values | 0-Disable 1-Enable |
Default | 1 |
Web UI | Phone > Multicast IP > Multicast Listening > Paging Priority Active |
Parameter | DBID_MULTICAST_PAGING_CODEC |
---|---|
Description | It configures the codec for multicast paging. |
Permitted Values | 0-G.711U 1-G.711A 2-G.722 3-G.729 4-G.723 |
Default | 2 |
Web UI | Phone > Multicast IP > Multicast Listening > Multicast Codec |
Parameter | DBID_MULTICAST_LISTEN_LIST |
---|---|
Description | It configures the multicast address and port number that the phone listens to and the label to be displayed on the phone screen when receiving the multicast paging calls. |
Permitted Values | Multicast IP address and port number: separated by ‘:’ (The IP address ranges from 224.0.0.0 to 239.255.255.255, and the port number ranges from 1024 to 65535.) Label: string |
Default | Blank |

Parameter | DBID_MULTICAST_PAGING_LIST |
---|---|
Description | It configures the IP address and port number of the multicast paging group in the paging list.And it configures the name of the multicast paging group to be displayed in the paging list. |
Permitted Values | Multicast IP address and port number: IP address: port (224.0.0.1-239.255.255.255 port: 0-65535) Label: string |
