MAXCS ACC 6.0 Administration Manual
•
Home Media Server ID —This configuration is meaningful for a multi-gateway
Softswitch system. When multiple chassis are configured to be a single system,
you need to assign IP extensions to the configuration’s Home Media Server to be
able to use its resources for activities such as the following:
•
Access voice mail
•
Initiate a conference call
•
Record a conversation
•
Barge in, listen, and coach by workgroup supervisor
Guidelines:
•
If the Softswitch and HMCP Media Server are in the same server, the default
ID “00” will be the
Home Media Server ID . No change is required.
•
If the HMCP Media Server and Softswitch server are separated, you need to
assign IP extensions to the HMCP Media Server ID .
•
If you have two or more HMCP Media Servers, you need to assign each IP
extension to one of them, based on resource usage.
•
Enable 3rd Party SIP Device —If the extension is a 3rd party SIP phone or other
device, check this box. You must have a license for each 3rd party SIP device.
•
Enable Fallback to Mobile Extension —When this option is checked, and the IP
phone loses its network connection, it will automatically fall back to a Mobile
Extension. The mobile extension channel must be specified from the drop-down
list. This feature is only available for an IP Extension with a dynamic IP address.
Losing network connection can happen in the following cases:
•
The user presses #26 to log out from the IP phone
•
The server loses connectivity to the IP phone
•
The IP Extension's channel is taken over by another extension
•
The user exits from an IP Talk session
Once associated with a fallback mobile extension, when the network connectivity
is restored, the fallback mobile extension stays active, and the user must re-
register the phone to reconnect to the server.
Setting VoIP Codec for IP Extension
The system has a pre-configured IP range and codec setting to assist IP phone
deployment.
In the Enterprise Manager/Codec profile, two codec profiles are pre-configured:
•
Default —Prefer G.723.1 support G.729
•
G.711 —G.711 with Jitter (10 ~ 60 ms), Packet Length 10 ms
In the Enterprise Manager/Servers/IP Codecs setting, three local IP address ranges are
pre-configured to use the G.711 codec profile:
•
192.168.0.0 ~ 192.168.255.255
•
10.0.0.0 ~ 10.255.255.255
•
172.16.0.0 ~ 172.31.255.255
When an IP phone registers to an IP extension, the system will check the IP address to
determine which codec to use for the IP phone.
