66 Enabling SIP Call Flow Diagrams in OVOC
You can configure the device to send SIP messages (in XML format) of SIP call dialogs to
AudioCodes One Voice Operations Centers (OVOC) so that OVOC management users can view
the call dialog as a call flow diagram. OVOC displays the call flow using vertical and horizontal lines
where the vertical lines represent the SIP entities (including the device itself) involved in the dialog
and where the horizontal lines represent the SIP requests and responses. An example of a SIP call
flow diagram in OVOC is shown below.
SIP call flow diagrams may be useful for debugging and for better understanding of the SIP call.
The call flow displays all the SIP messages related to the call session, including requests (e.g.,
INVITEs) and responses (e.g., 200 OK). For SBC calls, the call flow reflects messages as sent
"over the wire" - incoming messages before manipulation and outgoing messages after
manipulation. For Gateway calls, the call flow reflects incoming messages after Pre-Parsing
Manipulation (if configured) but before general Message Manipulation, and outgoing messages after
manipulation.
➢ To configure SIP call flow support:
1. Enable the OVOC call flow feature:
a. Open the Logging Settings page (Troubleshoot menu > Troubleshoot tab > Logging
folder > Logging Settings).
b. From the 'Call Flow Report Mode' [CallFlowReportMode] drop-down list, select Enable.
2. To send call flow messages of specific calls only (e.g., for a specific IP Group), configure a Log
Filter rule:
a. Open the Logging Filters table (see Configuring Log Filter Rules on page1096
b. Click New , and then configure the rule as desired, but with the following parameter
settings:
◆ 'Log Destination': Call Flow Server
◆ 'Log Type': Call Flow
