C20 audio issue

Hi,

I'm troubleshooting an issue at a customer site. They have several C20 codecs in the same building. Quality of service is configured the same for all C20 endpoints. One of these endpoints is having issues with audio (one way). It's not a permanent problem but it happens once or twice a week.

This problem always involves the same codec. This is a C20 codec running old software: TC3.1.1.220240

I made several test calls but could not reproduce the problem. I asked the customer to keep dates and time when this problem occures, this way I could find the following error messages in the audio0.log logfile:

Jan 30 16:07:09 (none) audio0: Err:AUDLOCALIN_doecReferenceDataHandler: Redundant ls reference buffer received, <seq 114854656>.

Like I said QOS is configured exactly the same for al C20's. Could this be a hardware/software problem? Or should I investigate the network some more?

Thank you in advance for your help,

Best regards,

Wouter
