Debugging call signaling 639
SmartWare Software Configuration Guide 52 • VoIP debugging
Explanation:
• The line
18:59:07 SIP_TR> Sent INVITE sip:60@172.16.32.33 SIP/2.0 indicates that the INVITE was
sent. Thus, call routing worked in context CS and the message left to the SIP network.
•
18:59:07 SIP_TR > Received SIP/2.0 100 Trying indicate that responses are received from the SIP net-
work. This means that IP connectivity is OK and the remote gateway can be reached. If there are no
responses, or negative ones, continue debugging the remote SIP gateway.
Using SmartWare’s internal call generator
The SmartWare has a powerful internal call generator that creates calls from the center of context CS. It is very
useful to debug call signaling or call routing problems to verify the correct working of one call signaling proto-
col at a time. Calls can be placed towards any interface on context CS, or any routing table within context CS.
Example: Debug ISDN protocol using the call generator. Create a call from context CS to an ISDN interface
called TERMINAL.

Command Purpose
call calling-party {accept | alerting |
dial|drop | inband-info | offer-state |
proceeding | reject-all | resume | sus-
pend | user-input } ....
Manipulates calls locally generated from the center
of context CS. To create a call, use “call calling-
party dial called-party”, to manipulate this call
afterwards use the same calling party. See the
examples below for usage.
