Can't figure out whats going on here and hoping someone can help got it hooked up to my sisters system but it wont dial her cell phone. If I pick up the extension I can hear the various dial tones but then I hear a busy. This seems to indicate the system did not properly dial out. For example the Duo requires you to dial 11 digits, 1 the then the area code and finally the number. If for example you just dial 10 digits or dial improperly you get a busy signal like I'm hearing now so I'm just wondering whats not being translated. Hoping someone can help.
