•
Adding HMCP licenses or changing assigned numbers does not require restarting the
MaxACD 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 MaxACD through WAN and
require the IP paging feature. The value will be the number of routers from MaxACD
to remote IP phone plus one.
Note: In order to use the QoS parameters in IP headers, you must first install the
NetFilter driver. To do this, run
setup.exe in the NetFilter Driver folder on your
MaxACD install CD.
Assign HMCP Resources to Extensions
After you configure the HMCP component, you need to configure extensions to use the
HMCP voice processing 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 MaxACD Server
For fewer than 200 agents, you may consolidate the MaxACD and HMCP into one server.
The IP extension Home Media Server ID should be assigned to "00" by default. You do
not need to change this number since both MaxACD and HMCP media server are in the
ID "00".
