*00: It will redial the last number called
From PhonePower Knowledge Base
Dialing *00 will redial the last number dialed from your Phone Power line.
To use:
Pick up the Phone Power Phone.
Once you hear a dial tone, dial *00.
The last phone number dialed from the phone will be dialed.
- Note - This will redial the phone number that was dialed using the Click2Call Feature on the Contacts page in My Account. Also, if the Remote Click2Call is used prior to dialing *00 from the Phone Power phone, a busy tone will be herd and the call will have to be dialed normally for the call to complete.
