You can do this remotely, but you need DISA. If you are gonig to complete this from outside the building
dial the DISA number
NPA-NXX-1234
When you hear the beeps, enter your SCOD, because I know you would have a SCOD if you are using DISA, XXXXXXX.
Then in one string you will dial
RCFD FFC + SCPW for the station + Prime DN of the station + 9+number you want to CFW to
Example:
8000+1234+1234+918005551212
I ususally have the SCPW the same and the Prime DN as it makes it easier for the user to remember.
You can allow users DISA access, but make sure you have a low enough NCOS setting for your DISA access.
And don't start with the "I would never use DISA as this opens your switch up to Tol Fraud" because if you are properly maintaining your system you won't be open to toll fruad. DISA can be utilized for this and for remote troubleshooting.
Hope this helps.
