I've had a few users mistakenly activate call forwarding on their phone to:
a) a number that is not valid (too few digits for an internal or external call, extension doesn't exist)
b) forward their phone to a valid external number but to a destination thats not approved (i.e. home, other business, etc.).
Is there a way to check the CFWD request initiated by a user via the handset to only use approved destinations? Perhaps restricting the CFWD to use only internal UC520 extensions or approved devices (specific cell phone numbers,etc.)
