Abstract

Apparatus and methods concerning routing of calls in an IPBX are disclosed. As an example, one apparatus includes an IPBX server configured to route VoIP calls for a plurality of end-users having respective VoIP-enabled devices communicatively coupled to the IPBX via a network. A user-activity detection circuit is communicatively coupled to the IPBX server. The user-activity detection circuit is configured to receive activity data indicating activity of end-users in a virtual office environment and receive event messages indicating statuses of pending calls in the IPBX server. The user-activity detection circuit determines user-activity statuses of the end-users based on received activity data and event messages. A computing server is communicatively coupled to the user-activity detection circuit and is configured to provide a set of services for one or more of the plurality of users as a function of the determined user-activity statuses of the end-user.

5. The apparatus of claim 4, wherein for at least one of the plurality of switchboard interfaces, the respective contact list includes a set of public contacts that are included in each of the contact lists and includes a set of private contacts that are exclusive to the respective contact list.

6. The apparatus of claim 3, further comprising a user-activity detection circuit communicatively coupled to the IPBX server and configured and arranged to

receive activity data indicating activity of the plurality of end-users in a virtual office environment,

receive event messages, from the IPBX server, indicating statuses of pending calls in the IPBX server;

and

determine the respective user-activity statuses of the end-users based on received activity data and event messages.

7. The apparatus of claim 3, wherein each of the plurality of switchboard interfaces is configured to

receive non-voice communications including short-message-service (SMS) messages, instant messages, electronic memos, email, or combinations thereof;

and

forward the non-voice communications to respective end-users included in the directory.

8. The apparatus of claim 3, wherein each of the plurality of switchboard interfaces is configured to

automatically answer incoming calls routed to the respective receptionist, when an auto-answer mode is enabled;

enable the auto-answer mode in response to a frequency of incoming calls to the receptionist being greater than a threshold frequency; and

disable the auto-answer mode in response to a frequency of incoming calls to the receptionist being less than the threshold frequency.

9. The apparatus of claim 2,

the switchboard sever includes a web server configured to provide a web-page configured to implement one of the switchboard interfaces when executed on a respective web-browser one of the receptionists;

the switchboard interface is configured and arranged to display a status of pending calls for the switchboard interface; and

the communicating of the pseudo-event messages for pending calls of the switchboard interface, by the call control circuit, restores statuses of pending calls displayed by the switchboard interface following reset by the web-browser.

10. The apparatus of claim 9, wherein the switchboard interface includes a graphical user interface (GUI) having a mechanism for selecting an action for a pending call for a switchboard interface, the action including answering the call, hanging up the call, placing the call on hold, sending the call to voicemail, forwarding the call to an end-user indicated in a directory, parking the call, or combinations thereof.

11. A method comprising:

routing, using a call routing circuit of an internet-protocol private branch exchange (IPBX) server, Voice over Internet Protocol (VoIP) calls for a plurality of switchboard interfaces, the switchboard interfaces corresponding to VoIP-enabled devices of a plurality of end-users and communicatively coupled to the IPBX via a circuit-based communications network;

initiating a new subscription, using a call control circuit coupled to the call routing circuit, for one of the switchboard interfaces in response to a subscription request from the switchboard interface;

providing, using the call control circuit, an event message indicating a status of a pending VoIP call to the switchboard interface in response to a change in a status of the pending VoIP call of one of the plurality of switchboard interfaces having an active subscription; and

in further response to the subscription request from one of the switchboard interfaces,

identifying a plurality of additional pending VoIP calls for the switchboard interface, wherein pending calls include active or previously requested calls; and

for each of the plurality of additional pending VoIP calls, communicating a pseudo-event message indicating a current status of the pending VoIP call to the switchboard interface, the pseudo-event message including historical data of the pending call, the historical data including data selected from the group consisting of;

call transfer history, length of call status, prior call status information, call parking information, and combinations thereof.

12. The method of claim 11, wherein the switchboard interface corresponds to a respective VoIP-enabled device of a receptionist, and the method further includes:
