Chapter 16: Setting Up IP Extensions
208 MaxCS 7.5 Administration Manual
• Home Media Server ID – This configuration is meaningful for a 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.
• SIP Registration Password – Polycom phones and other standard SIP 3rd-party IP phones require a
SIP Registration password to register the phone to the MaxCS server. The password should be the
same as the password that is configured in the Polycom IP phone configuration file. This password is
used only for phone registration purposes.
• 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 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 AltiGen 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 settings to assist IP phone deployment.
In Enterprise Manager, click the Codec button. In the Codec list, three codec profiles are pre-configured:
• G.711 Mu-Law
• G.729
• G.723.1
In Enterprise Manager, click Servers > IP Codecs tab. 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
