Assistance with multicasting

  • 1.  Assistance with multicasting

    Posted 13 hours ago

    I am working on a 3CX VOIP install for a school district. The server is hosted on  Hyper-V. New phones are supposed to be identified via pnp via 224.0.1.75. However, this is not working via two 2930 Aruba switches. I have attempted to manually configure the switches with IP igmp and static groups, but the 3CX server does not see the new phones come online. I could use a config example of how to get two switches configured with multicasting with the 3CX server connected to one of the switches.

    The server indicates it is listening on 224.0.1.75: ens192

    are you using VLAN trunking to the IP Phone? if so perhaps you can use DHCP option 132 to assign the VLAN for them and then igmp could kick in.
