Call Progress Details: Field Definitions (continued)
 
Field Name 
Values 
Description 
Supplementary Services Status 
 
Call on Hold 
alphanumeric 
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 screen of remote VOIP. 
Call Waiting 
alphanumeric 
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 screen of remote VOIP. 
Caller ID 
“Calling Party 
identifier”;  
“Alerting Party 
identifier”;  
“Busy Party  
identifier”; 
“Connected 
Party + 
identifier” 
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 screen of the remote VOIP unit. 
Call Status fields 
 
Call Status 
hangup, active 
Shows condition of current call. 
Call Control Status 
Tun, FS + Tun,  
AE, Mux 
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). 
Silence Compression 
SC 
“SC” stands for Silence Compression.  With Silence Compression 
enabled, the MultiVOIP will not transmit voice packets when silence is 
detected, thereby reducing the amount of network bandwidth that is being 
used by the voice channel. 
Forward Error 
Correction  
FEC 
“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
