Enter the following information.
Parameter |
Description |
Maximum call appearances | The maximum number of simultaneous call branches in which the SIP device can participate. If the Configured SIP Binding is used by one or more PBX Lines (which must be on different PBXs), this value controls the total maximum call appearances across all these lines; the lower of the two values applies. If there are active calls on this SIP device and you decrease this value below the number of active calls, those calls will not be dropped. However, new calls will not be possible until the number of current call appearances drops below this value. |
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 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. If there are active calls on this SIP device and you decrease this value below the current bandwidth usage, those calls will not be dropped. However, new calls will not be possible until the bandwidth usage drops below this value. |
Trusted | Specifies whether the NE should send the calling directory number (DN) to the SIP device if the caller withholds it. Values:
|
Use static NAT mapping | Specifies whether the NE should perform Network Address Translation on the contents of messages sent to this SIP device. Values:
|
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:
|
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). |
