I've had proposed a fix to SCA module in the tracker (https://sip-router.org/tracker/index.php?do=details&task_id=446) but did´t hear anything about it until now.

I would appreciate some comments on that to see if its feasible to be committed or even hear for anyone else using SCA module with Polycom phones to see if they have the same issue described.

Thanks,

João Vitor Arruda
