Are you on T-Mobile?
If so ... I am noting that all of my T-mo phones cannot connect to each other (just get a busy signal) and I suspect this is a system-wide problem unrelated to iPhones. My son's Samsung is doing this as is our @Home service. I can make calls to regular landlines but not within T-Mo. 611 is so overloaded I can't get through ... in other words, I think there is more to this than meets the eye!!
Cheers!!
