[Freeswitch-users] DTMF Star Event Inconsistent

Mon Oct 27 11:22:31 PDT 2008

I'm not an authority on this, but I have spotted some things that might help
you figure this out

Your events show up with different unique-ids - Unique-ID:
34b83622-a473-11dd-8207-2b46fcff01af
and Unique-ID: 34adac7a-a473-11dd-8207-2b46fcff01af
You should only be looking for events on only one unique-id.
If each ID is a leg of the call (Not sure about this) It also looks like
each leg has a different sampling rate ie PCMU and G722.

Hope this is helpful
