A couple of possible causes of a double ring in the US: 1) Rolm PBXs use the double ring. If the call terminated on a DID trunk into a Rolm machine, then the PBX generated the ring. Note that DID service implies that the PBX, not the CO, generates the tones. Hence some Rolm oddities: If the line is equipped with Autopark, then if you listen to the busy signal for ten seconds, it goes away and beeps the called party. The caller doesn't pay until the callee picks up. Clever. 2) The No. 1 Crossbar generated double ring on some numbers. Few are left in service but 703 is PacBell so there may be a few left ...
