Setting Voice over IP trace levels

There are two types of system trace available for Blueworx Voice Response Voice over IP:

• SIP stack trace, for tracing signaling errors.
• Media trace, for tracing RTP voice stream errors that are carried over the adapter.

Three levels of trace are available for each. Level 1 gives the least trace information and level 3 gives the most. Level 1 is the default.

To increase the amount of trace information recorded for either the SIP stack or media:

1. From the Welcome window, select Applications → Applications.
2. Double-click on the IBM_SIP_VOIP entry.
3. Select Custom Servers.
4. Double-click on SIP_VOIP.

   A Custom Server (SIP_VOIP) window opens.

5. Select File → Properties.

   A Properties (SIP_VOIP) window opens.

6. In the Main() args field, enter one of the following:

   -TS3

   to increase the SIP signaling trace to level 3.

   -TM3

   to increase the media trace to level 3.

   -T3

   to increase both the SIP stack trace and the media trace to level 3.

   To increase to only level 2, substitute a 2 in place of the 3 shown in these examples.

7. Click OK to close the window.
8. In the Custom Server (IBM_SIP_VOIP) window, select File → Save then File → Close.
9. Use the System Monitor window to disable your trunks and channels.
