On the Servers > VoIP > Modify Server page of the Allworx server, there are three

parameters used to configure where the server transmits zoned pages:

• Paging Base IP Address – This is the multicast base IP address used by

the system. Each paging zone uses the base address plus an offset.

Zone 0 (the overhead zone), uses an offset of 0, zone 1 uses an offset of

1, etc. For example, if the base address were set to 239.255.10.0, then

zone 2 would use multicast IP address 239.255.10.2.

• Paging Port – This is the UDP port number that the packets are sent to.

All zones use the same port number, but each has its own multicast IP

address.

• Paging Max Hop Count – This value controls the time-to-live (TTL) count

in the IP header of all paging UDP/RTP frames. Typically, this value is set

to 1 so that the packet will not be sent beyond the local subnet. However,

if you have multiple subnets with phones on them, this value will need to

be increased.
