Version 7.2 915 Mediant 1000B Gateway & E-SBC
User's Manual 59. Testing SIP Signaling Calls
The figure below displays an example of an SBC test call:
Figure 59-6: SBC Test Call Example
1. The call is received from the remote endpoint with the called number prefix
"8101".
2. As the 'SBC Test ID' parameter is set to "8", the device identifies this call as a
test call and removes the digit "8" from the called number prefix, leaving it as
"101".
3. The device performs the regular SBC processing such as classification and
manipulation.
4. The device routes the call, according to the configured SBC IP-to-IP routing rules,
to the proxy server.
5. The device receives the call from the proxy server.
6. As the 'Test Call ID' parameter is set to "101", the device identifies the incoming
call as a test call and sends it directly to the simulated test endpoint "101".
 To configure SBC call testing:
1. Configure the test call parameters (for a full description, see ''SIP Test Call
Parameters'' on page 954):
a. Open the Test Call Settings page (Troubleshooting tab > Troubleshooting
menu > Test Call folder > Test Call Settings).
Figure 59-7: Configuring SBC Test Call with Proxy
b. In the 'Test Call ID' field, enter a prefix number for the simulated test endpoint on
the device.
c. In the 'SBC Test ID' field, enter a called prefix number for identifying the call as
an SBC test call.
d. Click Apply.
2. Configure regular SBC call processing rules for called number prefix "101", such as
classification and IP-to-IP routing through a proxy server.
