All,

 

We have built sipxTapi to use the IPP codec. In general the performance is
good.

 

We are seeing at intermittent fault where jitter is introduced in packets
sent via the MediaProcessing library. 

 

In most cases the effect of this locally introduced jitter is
un-intelligible speech. Audio is impacted in both directions, although a
pcap trace shows no problems with the RTP stream coming in to the local
host.

 

Are there any known issues with locally generated jitter impacting the
latest 3.3.0 stream? Something is preventing the PCM data from being sent at
regular 20ms intervals locally.

 

Regards,

 

Rob Mansfield.
