Description Feature
Enter a string to configure the phone to listen for and initiate multicast paging. You
can add a phone to up to 10 paging groups. Enter the script in this format:
pggrp=<multicast-address>:<port>;<name=group_name>;<num=multicast_number>;
<listen=boolean_value>;<pri=priority_level>;<codec=codec_name>;
Example script :
pggrp=224.168.168.168:34560;name=GroupA;num=500;listen=yes;pri=1;codec=g711a;
• Multicast IP address (multicast-address) and port (port)—Enter the multicast IP
address and the port specified on your paging server. The port number must be
unique for each group and an even number within 1000 and 65534.
Make sure that you set the same multicast IP address and port for all the phones
within a paging group. Otherwise, the phones can't receive paging.
• Paging group name (name)—Optionally enter the name of the paging group. The
name helps you identify the paging group the phone is in when you have multiple
paging groups.
• Multicast number (num)—Specify the number for the phone to listen for multicast
paging and initiate a multicast paging session. Assign the same multicast number
to all the phones within the group. The number must comply to the dial plan
specified for the line to initiate a multicast.
• Listen status (listen)—Specify whether the phone listens for paging from this
group. Set this parameter to
yes
to make the phone listen for the paging.
Otherwise, set it to
no
, or don't include this parameter in the script.
• Priority (pri)—Specify priority between paging and phone call. If you don't specify
the priority or don't include this parameter in the script, the phone uses priority
1 . The four priority levels are:
• 0 : Paging takes precedent over phone call. When the phone is on an active
call, an incoming paging places the active call on hold. The call resumes
when the paging ends.
•
1
: When the phone receives an incoming paging on an active call, the user
hears the mix of the paging and the call.
• 2 : The user is alerted with the paging tone when receiving an incoming
paging on an active line. The incoming paging isn't answered unless the
active call is put on hold or ends.
• 3 : The phone ignores the incoming paging without any alert when the phone
is on an active call.
• Audio codec (codec)—Optionally specify the audio codec for the multicast paging
to use. The supported codecs are G711a, G711u, G722, and G729. If you don't
specify the codec or don't include the codec parameter in the script, the phone
uses G711u codec.
The first group comes with the default script:
pggrp=224.168.168.168:34560;name=Group_1;num=800;listen=yes;pri=2;codec=g722;
