Allworx 6x - Calls Dropping after on hold

We have an Allworx 6x running the latest software (8.4.4.7). The 92xx phones are also running the latest firmware.

We're having an issue with calls being put on hold and when the user goes to retrieve the call, there is just dead air. Neither user can hear anything and the call gets dropped. This also affects warm call transfers as the user is put on hold before being transferred.

Call parking and all other functions work just fine.

SIP line. I think we got the issue resolved by setting Allworx to only use u711 codec. I think the codec was changing while on the call.
