Thanks, I tried playing around with the DTMF Playback length and level, too, but no luck. The Auto setting will work with some services fine, and others get numbers repeated. If I enter 12345, it may be read as 12222334555. Anyway, Inband works reliably, just not with both voxalot at voipmich at the same time.
I also use Gizmo for most of my 800 number calls, but there have been a few times when I needed to make a call and Gizmo was out of service, so it's good to have alternates.
The best alternative I've found for sound quality is voipmich, and trxtel (though some numbers won't connect with trxtel). Tollfreegateway is an option, but I get bad jitter with it at times. Fwd and ideasip also have free 800 number service, but sound quality isn't as good for the calls I've made (and Fwd hasn't worked for a week or two now).
