Symptoms
When you have more than one SIP trunk on the Cube to different providers and want to mix between two flavor of the media flow()through/around) depending on the destination provider.
Media flow-through command under the dial peer is not affecting the call process and all calls completed as media flow around.
Diagnosis
The dial peer is configured with media flow-through command while the global configuration under voice service voip is configured as media flow-around which overrides media flow-through command on dial peers.
Solution
Switch the global configuration to media flow-through then add the command media flow-around to the desired dial peers.
