Sorry, I failed to mention that the alarm device is not connected to a POTS line. Actually, I don't have a POTS line. Also, I am trying to dial "*##" not "**#" (messed that up in my original post)
I have my OBI110 connected to the house telephone wiring and the alarm device is connected to that. So what I need is for the OBI to allow me to pickup the phone and dial "*##" and leave the line open while I interact with the alarm device without trying to route me to one of my VOIP providers.
More info:
On the OBI110 I have GV as SP1 and
VOIP.MS as SP2.
When I initially tried to dial "*## " I got a busy signal. Then I added |*##| to my "Phone Digit Map".
After I did that I could dial "*##" but then it said there was no route defined. So I tried adding {<:*##>} to my outbound call route.
Still not working.
