There are some limitations to the PIN-Free
Dialing function.
1. One phone number can be linked with ONLY one PIN number. However, one PIN number can be linked with up to five origination phone numbers.
2. The PIN-Free Dialing function will not
work if
a. the origination phone number has caller ID block;
b. the origination phone number is part of an office phone system and the caller ID shows the office's main number rather than the origination phone number.
In these situations, the Phone Switch will ask the caller to enter the PIN.
