218 MAXCS ACC 6.7 Administration Manual
•
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.
