Fastcall users with assigned phones can configure their devices to route inbound calls. The softphone checks each user’s status and rings only those who are available.
If a user is already on a call or offline, the call may be routed directly to their voicemail. When a different device is set (such as an office phone or mobile phone), the call will ring on that device instead. However, Fastcall loses visibility once the call is routed externally — we cannot detect the user’s real-time availability when the call is sent to a mobile or desk phone.
To help manage inbound calls, Fastcall includes an option for concurrent calls — also known as calls on hold. When using the softphone, Fastcall can present a second incoming call while the user is already on the line. The user can then choose to answer the new call, decline it, or allow it to continue ringing until it goes to voicemail.
Answering the 2nd call puts the first call on hold. The user can switch between calls as needed.

There is also an option to place an outbound call on hold to dial a 2nd outbound call.

Fastcall Admin Setting for Concurrent Calls
This option can be enabled by the Fastcall admin under Settings > Call Handling > Inbound Settings > Concurrent Calls.
This is an org-wide setting for all Fastcall users.

Note: Concurrent calls cannot be set when 3-way calling is enabled.
3-way calling is enabled for “listen-in” so that 3 parties may be on the call. The call setup Fastcall uses for the 3-way calling is not compatible with the concurrent call.
