Configuring Virtual Board HMCP
MAXCS ACM 6.7 Administration Manual 161
•
1,000 G.711 voice processing resources will be licensed to the system when one
HMCP Media Server license is registered.
• The more VPR assigned, the slower the system will be when it starts up. To calculate
the optimized number of VPR you need, use the following formula:
Total G.711 VPR = Total number of extensions X 2
Total G.711/723/729 VPR = Total number of remote IP phone users + Total Tie
Trunk Channels that will use compressed codec
• Adding HMCP licenses or changing assigned numbers does not require restarting the
AltiGen switching service.
•
In the event that you need to decrease the assigned numbers of HMCP resources
(reassigned to the second HMCP server, for example), the system must be rebooted
for the configuration to take effect.
Parameters in IP Header —QoS and TTL assignments.
QoS assignment —IP TOS/DiffServ Byte Value. The default TOS/DiffServ byte hex
value "A0" (10100000) signals the network switch and router that RTP packets are
"Critical". To set the value for Diffserv Code Expedited Forwarding (DSCP EF), you
can enter hex value "B8" (10111000).
TTL assignment —for IP paging multicasting only. The purpose of the TTL (Time To
Live) is to regulate how many hosts the IP paging packets can pass through. The TTL
value is reduced by one on every hop. You may need to adjust this value if there are
remote IP phones at different locations that register to MAXCS through WAN and
require the IP paging feature. The value will be the number of routers from MAXCS
to remote IP phone plus one.
Assign HMCP Resources to IP Extensions
After you configure the HMCP board, you need to configure extensions to use the HMCP
voice processing, conferencing, and recording resources.
In
Extension Configuration > General > IP Extension panel, change the Home
Media Server ID to the HMCP Media Server ID if necessary. Please refer to the following
scenarios.
Scenario 1 - HMCP Media Server inside Softswitch Server
For fewer than 200 users, you may consolidate the Softswitch and HMCP into one server
as shown below.
