SmartWare Software Configuration Guide

52 • VoIP debugging

Depending on the type of problem, some debug monitors are more useful than others. Try to avoid enabling all
monitors at the same time, as this generates a lot of output and can degrade system performance. The follow-
ing examples show some typical debug cases and what monitors should be switched on in these cases.

Example:

Debugging voice connections

Symptoms:

Voice quality is bad (dropouts), the voice connection is only established in one direction or not at

all, there is only noise instead of voice, no tones are played (e.g. dialtone).

Prerequisite:

The call is established from a signaling point of view (see chapters Debug H.323 Data and Debug

Session Control Data).

Use the following debug monitors:

Example:

Debugging Fax connections

Symptoms:

Fax transmission starts but is interrupted and the Fax machines terminate with an error message,

Fax transmission does not start at all, the unit’s firmware does not detect Fax.

[no] debug media-gate-
way rtp

Displays RTP related call parameters at call setup: local/remote IP
address and port, SSRC. During operation, displays periodically
updated statistics containing the number of sent and received packets,
the number of lost packets.
Usage: To verify that RTP packets are sent/received, and to debug net-
work quality issues (lost packets).

[no] debug media-gate-
way switch

Displays control activities on the TDM part of the Data Path.
Usage: To investigate problems with hair pinning or timeslot switching.

[no] debug media-gate-
way dsp

Displays control activities on the DSP including all call parameters (e.g.
the used codec).
Usage: To document the DSP parameters used for each call setup.

[no] debug media-gate-
way fax-data

Traces detected Modem and Fax tones.
Traces the flow of T.30 communication states between the fax machines.
Decodes the IFP (Internet Fax Protocol) elements within T.38 packets.
Displays T.38 related call parameters and operational errors like lost
packets.
Tracks the operation of the dejitter buffer used for T.38 Fax transmis-
sions.

Usage: To investigate problems with T.38 Fax and Modem transmissions in
general.

[no] debug media-gate-
way error

Displays detected errors over all the different parts of the Media Gate-
way.

[no] debug media-gate-
way all

Enables/Disables all Media Gateway monitors

Step

Command

Purpose

1

unit

#debug media-gateway rtp

tor

2
