•

: Dial the number 50, which calling-party 55 to 

the interface TERMINAL. If a phone connected to the port that binds to interface TERMINAL has MSN 
50 configured, it will start to ring. This is the case in our example.

•

You just have verified that ISDN layer1–3 and the context CS interface TERMINAL are configured so that 
a call with called-party 50 can be handled. If this is not the case (no response or a RELEASE message), con-
tinue debugging ISDN signaling.

•

: Drops the call initiated with the 

 command.

You can proceed as in this example with any other context CS interface, also for VoIP protocols like SIP 
and H.323.

There are several debug monitors that can help identify problems in VoIP connections. The most common 
VoIP problems are: voice quality problems (dropouts), fax transmission errors, no establishment of voice con-
nection, and wrong tone or playback. Dependent on the SmartNode devices, the output of the different Media 
Gateway monitors can differ.

An overview of all available Media Gateway debug monitors is given below. Some more specific examples for 
debugging cases follow after that.

Overview: Media Gateway debug monitors

Displays changes to the settings of the dejitter buffer, exceptions (under-
run, overrun, packet drops) and size changes. 
Usage: To investigate problems related to voice quality, voice packet 
payload sizes, delays, jitter

[no] debug media-gate-
way control [detail level]

Displays control activities on the Data Path (path of voice/fax data 
packets within your unit): State changes, tone start/stop, DTMF play-
back/detection, fax/modem detection.
Usage: To investigate problems with voice connections, DTMF, tone 
playback, fax and modem transmissions.
