Patton electronic SmartNode 4110 Series manual Using SmartWare’s internal call generator

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.

Command

Purpose

call calling-party{accept alerting dialdrop 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.

Example: Debug ISDN protocol using the call generator. Create a call from context CS to an ISDN interface called TERMINAL.

unit(cfg)#debug		ccisdn error
unit(cfg)#debug		isdn error
unit(cfg)#call 55			dial 50 dest-interface TERMINAL
