Bug Alert:

This bug alert applies only to those applications that disable local playback audio handling in the VOIP Media Engine v5.12.3.1 or v5.12.3.2:

Description:

The VOIP Media Engine has the ability to take its locally recorded audio stream (from the host’s multimedia hardware) and loop it back to the final local playback stream. The “looped back” record audio stream is then digitally mixed with all other audio streams that need to be played back on the host’s multimedia hardware.

If application software disables local audio playback, it should not call the following two API procedures:

     SetLocalAudioLoopback()
     SetLocalAudioLoopbackVolume()

Doing so will cause an access violation. The reason being is the internal master playback mixer that is responsible for mixing all data streams before final playback via multimedia hardware is not initialized when local audio playback is disabled.

This issue has been fixed. Now if an application disables local audio playback and calls these two API procedures, the procedures will return SipCallFailure.

This bug fix will be available in the v5.12.3.3 interim released scheduled for 7-14-06
