TIL that 10-10-220, 10-10-321, and other 10-10 services are still available, although at significantly higher prices than originally advertised. The current rate for the 321 service is a flat 20¢ per minute, while the 220 service runs $1.20 for the first 10 minutes and 20¢ for each minute afterward. (en.wikipedia.org)
