That seems to have done the trick, thank you very much!

jdoff,
When you dial a number on your rotary phone, do you get an extra touch tone after the called party has answered?
Thanks to MichiganTelephone, I am now dialing without issue. However, no matter how many rings it takes for the called party to answer, something (either the OBi or the DialGizmo) is generating a final touch tone (I think it's a "1") the instant the call is answered.
While annoying, it's not really a problem when calling a human. However, when calling an IVR system, the extra tone is an issue.

AndroidsOfTara,
It's a stab in the dark, but as an experiment, disable:
SPx -> X_SkipCallScreening : (unchecked)
and see if the unwanted DTMF '1' goes away.

I currently have that option checked (as in, not the OBi default), but I think I was able to temporally resolve it another way.
I remembered that the problem started when I updated the firmware from 2103 to 2283. I thought it was coincidental at first, but my touch tone phone (a 1978 ITT 2500) started having problems with that upgrade as well. I updated again to 2286 with no resolution.
The problem with the touch tone phone on 2283 and 2286 is that when making calls, the phone would go completely dead silent (and the microphone would stop working as well) as soon as the called party answered. I could still see activity on the OBi's LEDs, but the phone was unusable.
I figured that the rotary phone issue with the extra tone upon answer and this problem were related, but I didn't have time to deal with it, so I put a much newer ITT 2500 phone from the mid 90's on the desk and it worked fine.
I downgraded the firmware today back to 2103 and both issues have gone away. I can now make calls on a rotary phone without the extra tone and my 1978 ITT phone works again.
Something obviously changed between 2103 and 2283, but I don't know what. I'd like to have current firmware, but I also like having my preferred set of phones working.
So what do you think could be causing both of those issues to happen simultaneously with a firmware upgrade?
M105:
I suspect the dialgizmo is picking up that "click" when the phone is answered and interpreting it as 1 pulse. That prompts it to send DTMF tone for "1". You can probably also fool it with a hook flash.
I don't know if the device has a sensitivity adjustment but that is something you should look at.
