If any of you live in the southern part of the US and have Cingular wireless you may have noticed that sometime last week you started getting a message that says, "You must first dial the area code and then the number in order to make this call" or "Your call cannot be completed as dialed"
Well, as some of you may know BellSouth owns Cingular. Until recently, before the merger of AT&T wireless and Cingular were complete, Cingular strictly relied on cell tower to cell tower transmission of all of its calls. Starting on October 25th, Cingular starting using VOIP in conjunction with their cell service to ease traffic and reduce cost. This means that when you call now, you connect with a cell tower that connects to an "internet terminal computer" and this transfers your call over broadband land lines for most of the journey.
Just as you have to use the 10 digit number (with area code included) within Skype or say Charter telephone, you must also dial the area code now with ALL Cingular calls.
It's a real hassle to have to go in and add the area code to the 100's of local contacts I have. I just thought I would give you a heads up if you've been getting this message.
