Message |
Description |
Possible Explanation and Action |
---|---|---|
CFG file not found |
The name-based and default configuration file was not found on the TFTP Server. |
The configuration file for a phone is created when the phone is added to the Cisco Unified Communications Manager database. If the phone has not been added to the Cisco Unified Communications Manager database, the TFTP server generates a CFG File Not Found response.
|
CFG TFTP Size Error |
The configuration file is too large for the file system on the phone. |
Power cycle the phone. |
Checksum Error |
Downloaded software file is corrupted. |
Obtain a new copy of the phone firmware and place it in the TFTPPath directory. You should only copy files into this directory when the TFTP server software is shut down, otherwise the files may be corrupted. |

You can access the Call Statistics screen on the phone to display counters, statistics, and voice-quality metrics of the most recent call.
![]() Note | You can also remotely view the call statistics information by using a web browser to access the Streaming Statistics web page. This web page contains additional RTCP statistics not available on the phone. For more information about remote monitoring, see Cisco IP Phone Web Page. |
A single call can have multiple voice streams, but data is captured for only the last voice stream. A voice stream is a packet stream between two endpoints. If one endpoint is put on hold, the voice stream stops even though the call is still connected. When the call resumes, a new voice packet stream begins, and the new call data overwrites the former call data.
To display the Call Statistics screen for information about the latest voice stream, perform these steps:
Step 1 | Press Applications. |
Step 2 | Select Admin Settings. |
Step 3 | Select Status. |
Step 4 | Select
Call Statistics.

Interval Conceal Ratio |
Ratio of concealment frames to speech frames in preceding 3-second interval of active speech. If using voice activity detection (VAD), a longer interval might be required to accumulate 3 seconds of active speech. |
||
Max Conceal Ratio |
Highest interval concealment ratio from start of the voice stream. |
||
Conceal Secs |
Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds). |
||
Severely Conceal Secs |
Number of seconds that have more than 5 percent concealment events (lost frames) from the start of the voice stream. |
||
Latency |
Estimate of the network latency, expressed in milliseconds. Represents a running average of the round-trip delay, measured when RTCP receiver report blocks are received. When the RTCP Control Protocol is disabled, no data generates for this field and thus displays as 0. |
||
Max Jitter |
Maximum value of instantaneous jitter, in milliseconds. |
||
Sender Size |
RTP packet size, in milliseconds, for the transmitted stream. |
||
Sender Reports Received |
Number of times RTCP Sender Reports have been received. When the RTCP Control Protocol is disabled, no data generates for this field and thus displays as 0. |
||
Sender Report Time Received |
Last time at which an RTCP Sender Report was received. When the RTCP Control Protocol is disabled, no data generates for this field and thus displays as 0. |
||
Rcvr Size |
RTP packet size, in milliseconds, for the received stream. |
||
Rcvr Discarded |
RTP packets received from network but discarded from jitter buffers. |
||
Rcvr Reports Received |
Number of times RTCP Receiver Reports have been received. When the RTCP Control Protocol is disabled, no data generates for this field and thus displays as 0. |
||
Rcvr Report Time Received |
Last time at which an RTCP Receiver Report was received. When the RTCP Control Protocol is disabled, no data generates for this field and thus displays as 0. |
