Version 7.2 989 Mediant 1000B Gateway & E-SBC
User's Manual 63. Testing SIP Signaling Calls
63.5 Configuring DTMF Tones for Test Calls
By default, the device plays the DTMF signal tone "3212333" to remote tested endpoints
for answered calls (incoming and outgoing). For basic test calls (as described in
Configuring Basic Test Calls on page 989), the device can play only the configured DTMF
tones (or none, if not configured). For test call endpoints that are configured in the Test Call
Rules table, you can configure the device to play either DTMF tones or a tone from an
installed PRT file (Test Call Tone). For more information, see Configuring Test Call
Endpoints on page 981.
Note:
• You can configure the DTMF signaling type (e.g., out-of-band or in-band) using
the 'DTMF Transport Type' parameter. For more information, see ''Configuring
DTMF Transport Types'' on page 201.
• To generate DTMF tones, the device's DSP resources are required.
To configure played DTMF signal to answered test call:
1. Open the Test Call Settings page (Troubleshooting tab > Troubleshooting menu >
Test Call folder > Test Call Settings).
2. In the 'Test Call DTMF String' field, enter the DTMF string (up to 15 digits):

3. Click Apply.
63.6 Configuring Basic Test Calls
The Basic Test Call feature tests incoming calls from remote SIP (IP) endpoints to a
simulated test endpoint on the device. The only required configuration is to assign a prefix
number (test call ID) to the simulated endpoint. Incoming calls with this called (destination)
prefix number are identified by the device as test calls and sent to the simulated endpoint.
The figure below displays a basic test call example:
