SOrry, this is not really a callmanager or CME questions. Simple telephony question. Do all Long distance company require you to dial a 1. or is it just some long distance companies. If this is not mandatory for all long distance companies do any one know any specific companies that don't require the "1".
Generally most telcos require dialing a +1 (our country code) for long distance calls.
However, you can order a AT&T dedicated long distance circuit (full voice T1) that you can only send 10-digit calls to. They don't want the 1 on that type of circuit. Some providers also may request you prefix all calls with a character (for example 9). You have to confirm with the carrier, but generally North America sends long distance by dialing +1.
