Specify other Configured SIP Binding information

This step is optional.

Enter the following information.


Parameter

Description
Maximum call appearances The maximum number of simultaneous call branches in which the SIP device can participate. The default is 1024.
Maximum concurrent high bandwidth call appearances allowed The maximum number of simultaneous high bandwidth call branches in which the SIP device can participate. This value must not exceed Maximum call appearances. A value of zero (the default) indicates that the number of streams is limited only by Maximum call appearances. Changing this value changes the maximum IP bandwidth that may be taken up by calls associated with this device.
Trusted Specifies whether the NE should send the calling directory number (DN) to the SIP device if the caller withholds it. Values:
  • True
    The withheld calling DN is transmitted in the 'P-Asserted-Identity', and a 'Privacy' header is also included.
  • False
    The withheld calling DN is not transmitted.
Use static NAT mapping Specifies whether the NE should perform Network Address Translation on the contents of messages sent to this SIP device. Values:
  • True
    Select this value if the device is on a separate IP network from the NE and there is no Session Border Controller to provide the translation.
  • False
    Select this value if the device is on the same IP network as the NE, or if they are on separate networks and there is a Session Border Controller associated with the firewall between the networks.
Poll peer device Specifies whether the MetaSwitch NE should poll the peer device at intervals (specified by the Polling interval field) to check network connectivity. Values:
  • True
  • False
Polling interval The interval between poll messages sent to the peer device. This field appears, and a value must be specified, only if Poll peer device is set to True. Range: 1 - 3600 seconds (1 second - 1 hour).
