I'm running FusionPBX version 5.3.8. Inbound and outbound talls to/from extensions work fine. However, in a ring group which has several extensions plus an outbound external number, the origination to that number always fails, rejected by the VSP. In the CDR, it shows CODEC L16/L16 which is do not understand. I have onl ULAW enabled throughout the system.

A direct call dialed to the same external number from an extension goes through. What am I missing?
