Media Stream

Statistics about each active media stream are reported. The Media Stream header indicates the number of the media stream, and its statistics immediately follow this header.

State of the stream

State of the media stream indicated by the Media Stream header. Can be STREAM_ACTIVE, STREAM_ADDING, STREAM_CHANGING, STREAM_DEAD, STREAM_DELETING, STREAM_IDLE, or Invalid Stream State.

Stream Call ID

Identification of the stream call indicated by the Media Stream header.

Stream Type

Type of stream indicated by the Media Stream header. It can be dtmf-only, dtmf-relay, voice-only, or voice+dtmf-relay.

Negotiated Codec

Codec selected for the media stream. It can be g711ulaw, <G.729>, <G.726>, or No Codec.

Codec Payload Type

Payload type of the Negotiated Codec.

Negotiated Dtmf-relay

DTMF relay selected for the media stream indicated by the Media Stream header. It can be inband-voice or rtp-nte.

Dtmf-relay Payload Type

(Optional) Displays all Transport Layer Security (TLS) over TCP connection information.

udp

Displays all User Datagram Protocol (UDP) connection information.

Total active connections

Indicates all the connections that the gateway holds for various targets. Statistics are broken down within individual fields.

No. of send failures

Indicates the number of TCP or UDP messages dropped by the transport layer. Messages are dropped if there were network issues, and the connection was frequently ended.

No. of remote closures

Indicates the number of times a remote gateway ended the connection. A higher value indicates a problem with the network or that the remote gateway does not support reusing the connections (thus it is not RFC 3261-compliant). The remote closure number can also contribute to the number of send failures.

No. of conn. failures

Indicates the number of times that the transport layer was unsuccessful in establishing the connection to the remote agent. The field can also indicate that the address or port configured under the dial peer might be incorrect or that the remote gateway does not support that mode of transport.

No. of inactive conn. ageouts

Indicates the number of times that the connections were ended or timed out because of signaling inactivity. During call traffic, this number should be zero. If it is not zero, we recommend that the inactivity timer be tuned to optimize performance by using the timers command.

Max. tcp send msg queue size of 0, recorded for 0.0.0.0:0

Indicates the number of messages waiting in the queue to be sent out on the TCP connection when the congestion was at its peak. A higher queue number indicates that more messages are waiting to be sent on the network. The growth of this queue size cannot be controlled directly by the administrator.

Tuples with no matching socket entry

Any tuples for the connection entry that are marked with "**" at the end of the line indicate an upper transport layer error condition; specifically, that the upper transport layer is out of sync with the lower connection layer. Cisco IOS software should automatically overcome this condition. If the error persists, execute the clear sip-ua udp connection or clear sip-ua tcp connection command and report the problem to your support team.

Tuples with mismatched address/port entry

Any tuples for the connection entry that are marked with "++" at the end of the line indicate an upper transport layer error condition, where the socket is probably readable, but is not being used. If the error persists, execute the clear sip-ua udp connection or clear sip-ua tcp connection command and report the problem to your support team.

Remote-Agent Connections-Count

Connections to the same target address. This field indicates how many connections are established to the same host.

Remote-Port Conn-Id Conn-State WriteQ-Size

Connections to the same target address. This field indicates how many connections are established to the same host. The WriteQ-Size field is relevant only to TCP connections and is a good indicator of network congestion and if there is a need to tune the TCP parameters.

Last Clearing of Statistics Counters

Last time the statistics counters were cleared by means of the clear spe counters command.

Buffer Overflow Errors

The digital-signal-processor (DSP) buffer has overflowed. If overflow continues, data will be lost and voice will be distorted (as concealment is added).

Endpoint Detection Errors

A voice frame has arrived after a predefined timer expires, causing the DSP to declare it late. If the frame consists of the SID/marker bit, it causes an endpoint detection error and the late packet is included as an endpoint detection error.

Packets Received Early

The number of frames held in the delay buffer exceeds the expected playout delay — that is, the delay buffer is overrun (too many frames waiting to be played out for the expected playout delay). At this point, the buffer must reduce the excess delay using intelligent frame deletion to preserve audio continuity.

Packets Received Late

The DSP has received an out-of-sequence packet and started a timer for the missing packet. The packet has failed to arrive in time; it is marked as late and the statistic is incremented. The DSP does interpolative or silence concealment for any missing frames. This type of problem is apt to occur in a congested network and results in lost packets and diminished voice quality.

Bad Protocol Headers

Packets have been rejected for any of the following reasons: bad protocol header, incorrect length, unknown packet format, unknown Real-Time Transport Protocol synchronization source (SSRC), incorrect checksum (when the Extended header is used), cumulative number of packets with invalid RTP headers (the header extension exceeds the packet length), or an invalid User Datagram Protocol (UDP)/IP header if extended encapsulation is enabled.
