There is no such thing as a "long distance ring". What you are describing is probably what is known as "distinctive ring". By default, the ring pattern for SP1 is the typical USA ring pattern, of one ring, with silence, then another ring. The default ring pattern for SP2 is the USA ring pattern for a second inbound number, which is two shorter rings, then silence, then two more shorter rings, etc.
Is that what you mean? If so, you can change SP2 to the same ring pattern as SP1. One way to do that is:
Sign into your OBiTALK account on a web browser, click on your OBi device. Scroll down and click the blue "OBi Expert Configuration" button. Get past the warning message, and enter OBi Expert. Click the Ring Settings, then Ring Profile A, then copy and paste the ring pattern 1 values, overwriting the ring pattern 2 values and submit the change. You MUST un-check both boxes to the right of the setting to be able to edit it.
