Hey We have integrated AEC3 branch of the pjsip for enhanced echo cancellation support in existing 2.11 release. Quite often we are getting an error print: !Underflow detected... After which echo cancellation stops. Can you guys help me in understanding why this is coming and how can it be resolved?
