There are 3 of us in the office. I have an IWATSU ADIX 12KTD-2 phone; 2 others in my office have 12KTS-2 phones. The phones have been used in this company for a number of years.

Speed dialing is giving us some challenges. Previously, it worked for the former members of the company. Now, the ones with international numbers do not work. The ones for our country (U.S.) work fine as they always have. it is the international ones that aren't working any more.

Can anyone help me? thanks in advance!
