I see there are different kinds of MAT cables. MAT CA-Q, MAT CA-P, MAT CA-T.I am looking for which one to use with MCI integration to a Repartee Voice mail. I am also wondering what each kind is used for.I can't seem to find any documentation. My MCI integration will be from an AP00 card to the 9 pin com port on the PC. I am guessing one is 9 pin, one is 25 pin ect.
