[SR-Users] DMQ with dialog: KDMQ messages being looped back to the source

[Charles Chance]

Hi Pat,

In your config, do you exit immediately after handle_dmq_message()?

Are you able to share with us one of the looped messages, both as it is
received by B and then as it is sent back to A?

Cheers,

Charles
