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 it can display the call dialog as a call flow diagram (ladder). OVOC displays the call flow on the Call Flow page (Calls menu > Calls List tab > select call > Show button > Call Flow tab). The call flow is displayed using vertical and horizontal lines. The vertical lines represent the SIP entities (including the device itself) that are involved in the dialog. The horizontal lines represent the SIP requests and responses. An example of a SIP call flow diagram in OVOC is shown below. For more information on OVOC, refer to the document One Voice Operations Center User's Manual.

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.

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 Logging Filter Rules

b.

Click New , and then configure the rule as desired, but with the following parameter settings:

◆

'Log Destination': OVOC (QoE)
