Description

The phone receives RTP packets destined for this multicast IP address and port and plays them out.

Starting at version 8.7.3.26 you can setup the multicast address with additional options:

  • speaker=(0|1):If this option is set and value is 1, then the multicast audio will be played always over speaker. If value is 0, then the current audio device will be used. If this option is not set, then value 0 is used as default value.

  • interrupt=(0|1[|2(*)]):
    If this option is set and value is 1, then the multicast audio interrupts a running call. If multicast is finished, then the interrupted call continues. If value is 0, the multicast audio will only be played in idle state. If this option is not set, then value 0 is used as default value.
    (*)Starting with 8.7.5.75 and 8.9.3.67 the value can also be 2. If this value is set, then the call will be mixed with the multicast audio in a local conference.

  • volmax=(0|1):
    If this option is set and value is 1, then the maximal volume will be used for multicast audio. If value is 0, then the current volume will be used. If this option is not set, then value 0 is used as default value.

  • priority=(0..10):This option sets the priority of the multicast address. You can choose a priority between 0 and 10, where 0 is the lowest and 10 the highest priority. If the phone receives multicast from more than one configured port, then the multicast with the highest priority will be played. If they have the same priority then the multicast will be played, that was received first. If this option is not set, then a priority of 5 is used as default.

Starting at version 8.10.x, the name of the multicast zone is specified as an option::

  • name=<zone name>

Please note: for hold scenarios an incoming multicast is blocked with cw_dialtone = on (default). In case its required to received the multicast also if calls on, please set this to off.

Valid multicast IP and port:

ip:port

example: 239.255.255.230:5555

or alternatively starting at version 8.7.3.26, a comma separated key-value string with IP and port and optional parameters:

ip=ip:port[,speaker=(0|1)][,interrupt=(0|1)][,volmax=(0|1)][,priority=(0..10)]

example: ip=239.255.255.230:5555,speaker=1,interrupt=1,volmax=1,priority=9

starting at version 8.10.x, multicast zone name can be added as a parameter:

ip=ip:port[,speaker=(0|1)][,interrupt=(0|1)][,volmax=(0|1)][,priority=(0..10)][,name=<zone name>]

example: ip=239.255.255.230:5555,speaker=1,interrupt=1,volmax=1,priority=9,name=Page Zone A
