2.1. Skype for Business Internal Telephony

Skype for Business users can call each other via the Skype for Business platform. A user can only call the Direct Inward Dialing (DID) number registered with Skype for Business. The standard procedure of calling a DID number is used when double-clicking on a user name in the Skype for Business contact list. A call from one Skype for Business client to the other stays within the Skype for Business platform and will not be redirected to the NFON PBX or the PSTN.
