This is what I did:
I changed the frequency to 425-10.
The OBi110 has a combination of 2 frequencies.
Your example has the 2nd frequency as zero.
I assume this means it's no used, so I didn't include a 2nd.
Your example doesn't include a tone duration, so I keep them at default.
Dial at 20 seconds. Busy and Reorder at 10 seconds.
-1 for Ringback means ring forever.
I changed the cadence as specified in example.
