multicast paging not working

[semistatic]

I have the system setup for multicast paging, but none of the phones pickup and hear the page. I've confirmed that the autoprovision setting is in the phone, and that nothing in blocking multicast on the network.

 

Here are my paging extension settings:

Streaming mode: multicast

Destination: 3* 4*

Source: *

Multicast-address: 224.0.0.1:4000

Codec: ulaw

Record message: live playback

 

Is there some other setting besides "multicast on" and multicast IP address I need to check in the phones? We have 821s, 820s and 320s

 

Thanks,

Ryan

Can you check if the multicast address has been populated on the phone?

There were bugs in some firmware versions of the phone. The latest is 8.4.35 (see http://wiki.snom.com/Firmware/V8/Features).

The multicast is populating on the phone, and we're on 8.4.35 for the firmware

Can you tell us PBX version (including the OS) and if there are multiple network interfaces on the system?

Can you run the "route" command and see if there is an entry for multicast? Something like,

224.0.0.0 * 224.0.0.0 U 0 0 0 eth1

 

If not, please add a route using

route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
