MultiCast Paging CP860
For the life of me I can't figure out how to get multicast paging going on the CP860s.

Here is a list of things I have done so far, phones are auto provisioned with the following settings

multicast.codec = PCMU
multicast.receive_priority.enable = 1
multicast.receive_priority.priority = 0
multicast.listen_address.1.label = Page All
multicast.listen_address.1.ip_address =

I have configure two CP860 with the same above settings. On one of the phones I setup a DSSKey as Multicast Paging with the following value: which was unsuccessful.

In order to eliminate my network as the issue. I setup my sip server with the following routing table:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface         UG    100    0        0 em1   U     0      0        0 em1.20   U     100    0        0 em1     U     1004   0        0 em1.20       U     0      0        0 em1.20

And setup a windows desktop on vlan 20, with network card assign to vlan 20 as the highest priority card.

I then setup ffmpeg to multicast with the following command:
./ffmpeg -re -i ./test.mp3  -filter_complex 'aresample=8000,asetnsamples=n=160' -acodec pcm_mulaw -ac 1 -vn -f rtp udp://

And then proceeding to VLC open a network stream with the address:

My Desktop pc was able to successfully pick up the stream.

When initiating a page from the phone the syslog logs as follows:
Aug 10 23:13:59 Log [841]: TALK<6+info  >Local IP Address:
Aug 10 23:13:59 Log [841]: TALK<6+info  >Paging local_ip_address

I have tried these test with the following firmware:
And all have been unsuccessful.

If there is anything that I could do to further test the issue, or if you require any more information please don't hesitate to ask.
