You can view detailed information per voice port (channel). The information is grouped under the following tabs:
■ | SIP: Displays SIP-related information such as endpoint status (e.g., idle) and phone number |
■ | Basic: Displays information such as call duration. |
■ | RTP/RTCP: Displays RTP/RTCP-related information such as packet loss and network jitter. |
■ | Voice Settings: Displays voice-related configuration such as silence suppression. |
➢ | To view channel information: |
1. | Open the Monitor home page (see Viewing Device Status on Monitor Page). |
2. | On the graphical display of the device, click a telephony port. |
3. | From the shortcut menu, choose Port Status. |
