Configuring SBC Test Call with External Proxy
The SBC Test Call feature tests incoming SBC SIP call flow between a simulated test
endpoint on the device and a remote SIP endpoint, when registration and routing is done
through an external proxy/registrar server such as a hosted IP PBX in the WAN. In other
words, the complete SIP flow, including the path to/from the external proxy/registrar can be
tested.
Notes:
•
The SBC Test Call feature is initiated only upon receipt of incoming calls and with
the configured prefix.
•
This call test is done on all SIP interfaces.
As this test call type involves an SBC call, you need to configure regular SBC rules such as
classification and IP-to-IP routing. Therefore, this test call also allows you to verify correct
SBC configuration.
For this test call, you also need to configure the following call IDs:
Test Call ID - prefix number of the simulated endpoint on the device.
SBC Test ID - prefix number of called number for identifying incoming call as SBC test
call. The device removes this prefix, enabling it to route the call according to the IP-to-
IP Routing rules to the external proxy/registrar, instead of directly to the simulated
endpoint. Only when the device receives the call from the proxy/registrar, does it route
the call to the simulated endpoint.
The figure below displays an example of an SBC test call:
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".
