I only can say for the obi202, but on that, sp1 is set to profile A, and SP2 is set to profile B. What I did on mine was I wanted to change my ring tone back to more of a regular ring tone, like I had with the POTS line, or my VOIP service I had before this. What mine was doing was 2 quick rings, then a 2 second delay, and repeat. I went into profile b under ring settings, unchecked the default box under ring settings so the ring pattern box could be edited, and changed it to 60;(1+3) As far as I know, you need the 60; and the () there, but the numbers that associate inside the () are the timers. For example, on mine, the 1+3 are mean ring for 1 second, wait 3 seconds, and then repeat to ring for one second and wait for 3 more seconds. You can have partial seconds too, so if you have say .5+2, then it will ring for a half a second, and then wait 2 seconds. The X_Default ring is directly related to the ring sequence under number under the ring profile. which I believe is set to the 1st ring sequence by default, you will have to uncheck the default button and select a different number other then 1 to get a different ring sequence.
