In the Calls gateway overview page, all calls actively being made can be monitored. This is advantageous for diagnostic purposes in particular, since the existence of possible network problems, for example, is immediately visible (see Coder):
- Interfaces: Display of the calling interface.
- Protocol: Display of the protocol used on the calling side.
- Coders: Display of the coder used on the calling side, for example, G711AB(2,0,0). The values in brackets have the following meaning for voice coders, in order:
- Round trip = Transit time in ms of a data packet from A to B and back again.
- Jitter = Latency time in ms (time interval from the end of an event up to the start of the response).
- Loss = Number of lost packets (packet loss).
- Coders: For T.38 calls the values in brackets hace a different meaning
- Pages = Number of transmitted pages.
- Speed = Speed in bits/seconds for the fax highspeed data.
- Loss = Number of lost packets (packet loss).
- Number: Display of the called number.
- State: Possible states: Alerting, Calling, Connected, Disconnecting.
