We upgraded our TL MT from version 9.0.2 to the latest 9.1.2-37, and are now getting a new error in the /var/log/asterisk/messages and full logs listed below. This appears to only happen on inbound calls when the billable flag is set on an inbound route.
WARNING[Unique Call ID] pbx_builtins.c: The SetAMAFlags application is deprecated. Please use the CHANNEL function instead.
Any info on this and how to correct is appreciated.
