PrimaryLine -> PSTN Line

When I press any Speed Dial key and do not press # it takes 10 seconds to respond.
I copied all your settings into my OBi and Speed Dials respond in 4 seconds as expected.
If all else fails, reset the OBi to factory defaults and restore the very same settings back into it.
Sure enough. That looks like it took care of the issue.
