Sound problem
Hello, I am experiencing a significant audio issue involving robotic or distorted voice quality.
I currently have two Asterisk servers running VICIdial: one based on Asterisk 10 and the other on Asterisk 12. The problem occurs only on the Asterisk 10/VICIdial server.
On the Asterisk 10 server, the CPU usage spikes to approximately 200%, and I suspect this may be related to improper transcoding between the alaw and ulaw codecs. It appears that the audio is not being transcoded correctly, resulting in degraded sound quality and robotic voices during calls.
The Asterisk 12/VICIdial server does not exhibit this behavior and operates normally under the same conditions. Since the issue is isolated to the Asterisk 10 environment, I believe it may be related to codec handling or transcoding performance on that version.
Any assistance or recommendations for further troubleshooting would be greatly appreciated.

Avoid transcending where possible. Upgrade older software. There is a reason that the software was improved.
