To receive telephone calls from the 8x8 Contact Center application, agents must have access to one of the following types of telephone connection:
- Public switched telephone network (PSTN) connection.
- Voice over IP (VoIP) connection.
For both VoIP or PSTN telephones, the telephone assigned to the 8x8 Contact Center must:
- Always be available to receive incoming calls.
- Not forward calls to a non-8x8 Contact Center voicemail box before 8x8 Contact Center can offer an incoming call to an agent, and forward that call to an agent's 8x8 Contact Center voicemail box if no agent accepts the call.
