Call Flow for a Branch Office
Branch call flow begins with a Virtual Number on your PBX and flows to the receptionist at the branch office. In this case, the receptionist can be a live operator, an Auto Attendant, or several live operators assembled in a ring group or call queue. In summary, a receptionist for Branch Office receives inbound calls through one of the following roles:
- Auto Attendant
 - Live Attendant (receptionist)
 - Multiple receptionists with a call queue
 - Multiple receptionists with a ring group
 
Call flow within a branch office may be explained as follows:
- The branch is assigned a Virtual Number. The Virtual Number points to the receptionist extension that is assigned as the Receptionist of the branch office.
 - Overflow calls to branch office receptionist can go to voicemail, Auto Attendant, or any forwarding phone number. The receptionist extension is where you set call overflow rules, if required.
 - The caller can leave a voicemail or dial <0#> to be directed to the Branch Receptionist in order to ensure the caller gets a desired response.

Receptionist Tools
The receptionist receives branch phone calls. 8x8 provides receptionist with tools to distribute calls using:
- 8x8 Switchboard Pro, an HTML5 browser-based call management client
- Switchboard Pro is an application specially designed for handling inbound calls, voicemail, chat and notes. Switchboard Pro enables your receptionist to view real-time presence, manage multiple calls (call park, hold, transfer), coordinate with other receptionists, and toggle Auto Attendant.
 - Switchboard Pro is currently designed to work alongside Polycom desk phones.
 - Call Parking has three modes:
- Public Call Parking, which parks the call on an extension that is available for anyone on the PBX to pick up the call.
 - Branch Call Parking, which parks the call on an extension only available for pickup by an extension defined as part of the affected branch office.
 - Extension or Private Call Parking, which parks the call on a specific extension, only allowing retrieval from that particular extension.
For example, the receptionist parks the call on extension 1101, which belongs to Jane Davis. As a result, the parked call can only be picked up from Jane's extension. 
 
 - BLF keys on Polycom desk phone to monitor and transfer calls
 - Paging (over speakerphone or overhead PA system) to announce call parking
