Re: [asterisk-users] Sangoma transcoding card bug - drops audio samples
No, there are no visible errors. We performed several simulation tests in our lab to debug the problem. Every time there was jitter in the simulated network the card was dropping audio samples and the voice was illegible. I am wondering if anyone tested Digium in such conditions. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Sangoma transcoding card bug - drops audio samples
If you are getting like this dropped packets then nothing to worry.. thisis just an cli message in my case I face this but there is no voice delay in actual call.
