[asterisk-users] Sangoma transcoding card bug - drops audio samples
There is a serious bug in Sangoma transcoding cards. The card has an internal, small jitter buffer and it drops samples from the audio stream when there is high jitter in the network. The bandwidth is cheap now so for me the only reason to use transcoding is where I have low-bandwidth-high-jitter links. Sangoma said they will not fix it and we had to go back to software transconding. Do you have any experience with using Digium cards in such scenario? -------------- next part -------------- An HTML attachment was scrubbed...
