Description
Describes held call by its IP address source, location/gateway identifier, and hold duration. Location/gateway identifiers come from Gateway Name field in Phone Book Configuration window of remote VOIP.
Describes waiting call by its IP address source, location/gateway identifier, and hold duration. Location/gateway identifiers come from Gateway Name field in Phone Book Configuration window of remote VOIP.
This field shows the identifier and status of a remote VOIP (which has Call Name Identification enabled) with which this VOIP unit is currently engaged in some VOIP transmission. The status of the engagement (Connected, Alerting, Busy, or Calling) is followed by the identifier of a specific channel of a remote VOIP unit. This identifier comes from the “Caller Id” field in the Supplementary Services window of the remote VOIP unit.
Shows condition of current call.
Displays the H.323 version 4 features in use for the selected call. These include tunneling (Tun), Fast Start with tunneling (FS + Tun), Annex E multiplexed UDP call signaling transport (AE), and Q.931 Multiplexing (Mux).
“SC” stands for Silence Compression. With Silence Compression enabled, the MultiVOIP does not transmit voice packets when silence is detected, thereby reducing the amount of network bandwidth that is being used by the voice channel.
“FEC” stands for Forward Error Correction. Forward Error Correction enables some of the voice packets that were corrupted or lost to be recovered. FEC adds an additional 50% overhead to the total network bandwidth consumed by the voice channel. Default = Off
