I am having a problem with my HTC Sense. With certain phone numbers it will allow me to send and receive text messages, but when I try to call that number the phone call does not go through. I get either a busy signal or a message that my call can not be completed as dialed. But when that person calls me it recgonizes the number. I can not figure out why it will recgonize the number from a text msg, and an inbound call, but I can't call that number. Any advice would be apperciated.
