Abstract

Modifications to the call acceptance process in a call handler allows determination of how to process a call before the call is answered. In one embodiment a call handler receives an incoming call notification message that include call related information, such as the calling and called telephone numbers. A call acceptance timer is started after the incoming call notification message is received. Prior to accepting the call, the call handler uses the call related information to ascertain an appropriate queue and an available agent in that queue. If an appropriate agent is available, the timer is stopped, the call is accepted, and the call is routed to the appropriate agent. If an agent is not available, then upon expiry of the timer, the call is accepted and an announcement may be played to the calling party, while awaiting for an agent to become available.

First claim

The invention claimed is:

1. A method for processing an incoming call comprising a voice call at a call handler in a contact center wherein the incoming call originates from a calling party, the method comprising:
receiving a call establishment request at an interface to a carrier offering the incoming call to the call handler, wherein the call establishment request includes a number corresponding to a telephone number dialed by the calling party;
starting a call acceptance timer in the call handler after receiving the call establishment request, wherein expiry of the call acceptance timer causes the call handler to send a call acceptance message to the carrier accepting the incoming call;
using the number corresponding to the telephone number dialed by the calling party to ascertain a group comprising one or more agents configured to accept calls directed to the telephone number;
queuing the incoming call for the group prior to accepting the incoming call;
detecting in the call handler an event comprising an earlier occurrence of one of:
an agent from among the group is available to accept the incoming call prior to an expiry of the call acceptance timer, and
the expiry of the call acceptance timer has occurred prior to the agent becoming available to accept the incoming call;

sending the call acceptance message over the interface to the carrier accepting the incoming call in response to detecting the event;
routing the incoming call to the agent if the agent is available to accept the incoming call prior to the expiry of the call acceptance timer; and
providing an announcement to the calling party if the agent is not available to accept the incoming call prior to the expiry of the call acceptance timer.

2. The method of claim 1 , wherein the call establishment request is a Q.931-based ISDN SETUP message and the call acceptance timer is started in response to receiving the Q.931-based ISDN SETUP message.

3. The method of claim 1 , further comprising:
providing a second announcement to the calling party prior to sending the call acceptance message.

4. The method of claim 1 , wherein sending the message over the interface to the carrier to accept the incoming call comprises sending an ISDN CONNECT message and wherein receipt of the ISDN CONNECT message causes billing to commence by the carrier.

5. The method of claim 1 , wherein the call establishment request is a SIP-based INVITE message.

6. The method of claim 2 , wherein a PROGRESS message is sent after the SETUP message.

7. The method of claim 6 , wherein an ALERTING message is not sent prior to sending the call acceptance message.

8. A system for processing an incoming call to a contact center from a calling party, comprising a processor configured to:
receive a call establishment request from a carrier at the contact center, wherein the call establishment request includes a number corresponding to a telephone number dialed by the calling party;
start a call acceptance timer in response to receiving the call establishment request, wherein expiry of the call acceptance timer causes a call acceptance message to be sent to the carrier accepting the incoming call, wherein the call acceptance timer expires in response to an event comprising an earlier occurrence of:
a passage of pre-determined amount of time, and
an agent from a group of one or more agents becoming available prior to the passage of the pre-determined amount of time;

use the number corresponding to the telephone number to ascertain the group of one or more agents configured to accept calls directed to the telephone number prior to sending the call acceptance message;
determine that none of the group of one or more agents are available to accept the incoming call;
determine the expiry of the call acceptance timer has occurred prior to the agent from the group of one or more agents becoming available to accept the incoming call;
send the call acceptance message to the carrier thereby accepting the incoming call in response to the expiry of the call acceptance timer; and
provide an announcement to the calling party after sending the call acceptance message.

9. The system of claim 8 , wherein the processor is further configured to:
receive an indication that the agent from the group of one or more agents has become available to accept the incoming call after the announcement is provided; and
connect the calling party to the agent.

10. The system of claim 8 , wherein the call acceptance message is a Q.931 ISDN CONNECT message.

11. A system for processing an incoming call in a contact center from a calling party, comprising a processor configured to:
receive at the contact center a call establishment request from a carrier on a signaling interface, wherein the call establishment request includes a number corresponding to a telephone number dialed by the calling party;
start a call acceptance timer after receiving the call establishment request, wherein expiry of the call acceptance timer causes a call acceptance message to be sent on the signaling interface to the carrier accepting the incoming call;
use the number corresponding to the telephone number to ascertain a group of one or more agents configured to accept calls directed to the telephone number;
detect an event comprising an earlier occurrence of one of:
an agent of the group of one or more agents is available to accept the incoming call prior to an expiry of the call acceptance timer, and
the expiry of the call acceptance timer has occurred prior to the agent becoming available to accept the incoming call;

send the call acceptance message to the carrier on the signaling interface accepting the incoming call, after detecting the event;
route the incoming call to the agent if the agent is available to accept the incoming call prior to the expiry of the call acceptance timer; and
provide an announcement to the calling party if the agent is not available to accept the incoming call prior to the expiry of the call acceptance timer.

12. The system of claim 11 , wherein the call establishment request is a Q.931-based ISDN SETUP message and the call acceptance timer is started in response to receiving the SETUP message.

13. The system of claim 11 , wherein another announcement is provided to the calling party prior to sending the call acceptance message.

14. The system of claim 12 , wherein the message sent to the carrier to accept the incoming call is a Q.931-based ISDN CONNECT message.

15. The system of claim 12 , wherein a PROGRESS message is sent after the SETUP message.

16. The system of claim 12 , wherein an ALERTING message is not sent prior to sending the call acceptance message.

17. The system of claim 11 , wherein the call establishment request is a SIP-based INVITE message.

18. A non-transitory computer readable medium storing instructions that when executed cause a processor to:
receive a call establishment request on a signaling interface from a carrier at a contact center for an incoming call comprising a voice call, wherein the call establishment request includes a number corresponding to a telephone number dialed by a calling party;
start a call acceptance timer after receiving the call establishment request, wherein expiry of the call acceptance timer causes a call acceptance message to be sent to the carrier on the signaling interface accepting the incoming call, wherein the call acceptance timer expires upon an earlier of:
a passage of a predefined amount of time, and
an agent from a group of a plurality of agents becoming available
