Using Media Gateway Control Protocol (MGCP)

MGCP Troubleshooting

Making a Call

The MGCP phone is powered up properly but plays an error tone while
making a call.

Check to confirm the network connection and default gateway status.

The MGCP phone plays a call-progress tone.

The MGCP phone will play the call-progress tone while trying to establish a call
and this can take time. If it takes a long time, check to make sure the MGCP
call agent is running properly.

The MGCP phone plays an error tone.

The called party may not be registered with the proxy server.

The MGCP phone plays an error tone after an extended period of time.

The call agent is not running and the MGCP phone times out before playing an
error tone. This can take some time.

The voice quality is poor.

The MGCP phone supports packet loss and network jitter to some extent. Above
certain levels, voice quality can deteriorate. The G.729 codec will perform better
than the G.711 codec and can be selected in the configuration.

The call-hold feature does not work properly.

The call-hold feature requires cooperation from both ends of the call and from
the Call Agent. The behavior is not defined if the other phone and Call Agent do
not support the hold feature.

The speakerphone does not work.

The MGCP phone has a speaker to support one-touch dialing, but not for normal
speakerphone use. The other party will hear you if you are in speaker mode but
the voice on the speaker may be of poor quality.

Browser Access

There is no response from the phone through the browser.

Check if the MGCP phone is connected to the network and if you have the
correct IP address for the phone.
