  • FIG. 7 shows a system for call leg selection in accordance with another embodiment.
  • An aspect of this specification provides a system for selecting a call leg comprising a call manager connected to a telephony network for receiving an incoming call destined for a telephone number.
  • the call manager is configured to maintain a list of telephones each having the telephone number.
  • the call manager is further configured to send a query to each of the telephones for identifying which of the telephones is designated to receive the incoming call.
  • the call manager is further configured to receive responses to the query and based on the responses to route the incoming call to a designated one of the telephones.
  • System 50 comprises a first telephone 58 that is used by a first subscriber S- 1 .
  • Telephone 58 is connected to a telephony network 62 .
  • Telephone 58 and network 62 can be based on any known or future contemplated telephony infrastructure including, the public switched telephone network (“PSTN”), and/or a packet switched network such as a cellular telephony network and/or the Internet, and/or combinations thereof.
  • PSTN public switched telephone network
  • packet switched network such as a cellular telephony network and/or the Internet
  • Telephony network 62 is connected to a call manager 66 .
  • Call manager 66 is also connected to a phone such as a telephone 70 - 1 via a link 74 .
  • Telephone 70 - 1 can be an Internet telephone depending on the nature of link 74 . However, this is a non-limiting example and indeed link 74 can be based on a wide area network, (or even network 62 itself or portions thereof) or a local area network, whether or not wired or wireless, and combinations thereof, Telephone 70 - 1 thus represents an extension that is managed by call manager 66 .
  • Telephone 70 - 1 is operable to conduct telephony calls, whether incoming or outgoing, over network 62 .
  • call manager 66 can be embodied in the form of a server or other computing device.
  • a server can be based on a typical computing architecture comprising of an arrangement of one or more central processing units that connect to one or more memory units in the form of i) volatile storage (e.g. random access memory), or non-volatile storage (e.g. a hard disc drive, read only memory) or both.
  • volatile storage e.g. random access memory
  • non-volatile storage e.g. a hard disc drive, read only memory
  • Such a server typically includes one or more network interfaces for connecting the processor to network 62 .
  • the components of the server are typically interconnected by a bus and executing appropriate operating systems and system software to achieve the functionalities described herein.
  • Those skilled in the art will now recognize other electronic circuitry configurations, now known or future contemplated, for call manager 66 are contemplated.
  • Telephony network 62 is also connected to a wireless base station 78 which is operable to carry telephony calls associated with network 62 on behalf of a wireless telephone 70 - 2 via wireless link 82 .
  • Wireless link 82 is based on any known or future contemplated wireless telephony links including the Global System for Mobile communications (“GSM”), Code Division Multiple Access (“CDMA”) and/or IEEE 802.11 and/or Bluetooth and/or variants thereof and/or combinations thereof and/or successors thereto.
  • Wireless base station 78 is typically one of a plurality of base stations found as part of a wireless network operated by a wireless telephony carrier.
  • telephones 70 - 1 and 70 - 2 can each have the same telephone number, referred to herein as XXX-XXXX.
  • a shared line configuration or similar may be used to identify the phones as part of a set of phones that should be alerted when one of the phones in the set is alerted. Accordingly, when subscriber S- 1 dials XXX-XXXX into telephone 58 , either telephone 70 can be used to answer that call in accordance with the teachings herein.
  • Call manager 66 represents itself to network 62 as being the destination for phone number XXX-XXXX such that a call initiated at telephone 58 for XXX-XXXX will be routed through network 62 until it reaches call manager 66 .
  • Call manager 66 is configured to route such an incoming call to either telephone 70 in accordance with the teachings herein.
  • Call manager 66 maintains a configuration that indicates that number XXX-XXXX is associated with both telephones 70 , associating the number XXX-XXXX with a device address associated with each telephone 70 .
  • a device address can be based on, for example, the International Mobile Equipment Identity (“IMEI”) associated with telephone 70 - 2 .
  • IMEI International Mobile Equipment Identity
  • the device address for telephone 70 - 1 can be the Media Access Control (“MAC”) address for telephone 70 - 1 .
  • MAC Media Access Control
  • Other types of device addresses will now occur to those skilled in the art.
  • the device address can simply be a mapping between telephone numbers. In other words, assume that telephone 70 - 1 has the telephone number XXX-XXX while telephone 70 - 2 has another telephone number YYY-YYY.
  • call manager 66 can then maintain a mapping configuration that indicates that XXX-XXXX is mapped directly telephone 70 - 1 via telephone number XXX-XXXX and is also mapped indirectly to telephone 70 - 2 by mapping telephone number XXX-XXXX to telephone number YYY-YYYY.
  • call manager 66 can be based on the infrastructure of a private branch exchange (“PBX”), although other functionally similar infrastructures such as Ascendent Mobility, or GrandCentral are contemplated.
  • PBX private branch exchange
  • Telephones 70 are also each operable to exchange signaling information with call manager 66 .
  • signaling information can be delivered and received using any desired protocol, but in a present embodiment the Session Initiation Protocol (“SIP”) is employed.
  • SIP Session Initiation Protocol
  • call manager 66 is configured, upon receipt on an incoming call for XXX-XXX, to send signaling information to each telephone 70 to query as to which telephone 70 should be used to actually receive the call.
  • telephones 70 are each configured to use signaling information that is responsive to the query from call manager 66 which indicates which telephone 70 should be used to actually receive the call.
  • telephones 70 can be embodied in the form a computing device or other suitable electronic hardware.
  • An exemplary computing device can be based on a typical computing architecture comprising of an arrangement of one or more central processing units that connect to one or more memory units in the form of i) volatile storage (e.g. random access memory), or non-volatile storage (e.g. a hard disc drive, read only memory) or both.
  • volatile storage e.g. random access memory
  • non-volatile storage e.g. a hard disc drive, read only memory
  • Such a computing device typically includes one or more network interfaces for connecting the processor to network 62 .
  • Such a computing device also includes input devices such as a microphone and a keypad, and output devices such as a earpiece or speaker and a display.
  • the components of the computing device are typically interconnected by a bus and executing appropriate operating systems and system software to achieve the functionalities described herein.
  • Those skilled in the art will now recognize other electronic circuitry configurations, now known or future contemplated, for telephone 70 are contemplated.
  • Method 200 can be performed using system 50 but it should be understood that method 200 can be performed using other systems. However, to help further assist in understanding method 200 and system 50 , method 200 will be explained assuming it is performed using system 50 . Of particular note is that in system 50 , method 200 can be performed on by a server used to implement call manager 66 .
  • a query is sent to each of the telephones associated with the incoming call.
  • the query is sent using the previously-discussed signaling protocols that are known to both call manager 66 and telephones 70 .
  • Manager 66 utilizes the previously-discussed device addresses for each telephone 70 in order to route the respective queries.
  • Each query asks its destination telephone 70 as to which telephone should receive the incoming call C.
  • Step 210 is represented in FIG. 4 , as a first query Q- 1 is sent to telephone 70 - 1 via link 74 , and a second query Q- 2 is sent telephone 70 - 2 via base station 78 . While queries Q are being sent, call C is held at manager 66 , perhaps continuing to generate a ring-back for subscriber S- 1 at telephone 58 .
  • a response to each query is sent from each of the telephones to manager 66 .
  • the response is sent using the previously-discussed signaling protocols that are known to both call manager 66 and telephones 70 .
  • One of the responses indicates to manager 66 that the telephone 70 sending the response is the telephone which should receive the incoming call C.
  • telephone 70 - 2 has been set to receive the incoming call C.
  • telephone 70 - 2 will send a response at step 215 that indicates that telephone 70 - 2 should receive call C
  • telephone 70 - 1 will send a response indicating that telephone 70 - 1 will not receive call C.
  • Step 215 is represented in FIG.
  • telephones 70 are configured to be responsive to queries as contemplated in steps 210 and 215 .
  • Step 220 the call is routed to the telephone as designated from the response received at step 215 .
  • manager 66 will cause call C to be transferred to the appropriate telephone 70 .
  • Step 220 is represented in FIG. 6 , as call C is shown being routed from manager 66 to telephone 70 - 2 , thereby establishing a connection from telephone 58 to telephone 70 - 2 , such that subscriber S- 1 can speak with subscriber S- 2 .
  • a particular telephone 70 is designated as being set to receive incoming calls is not particularly limited.
  • mechanisms can be provided, as desired, to ensure that only one telephone 70 is set to receive incoming calls, and likewise ensuring ensure that responses R to queries Q made at step 215 will only have one response R that indicates that call C should be routed to a given telephone 70 .
  • system 50 can be configured so that only one response R indicates where call C should be routed.
  • Exemplary mechanisms include a manual process whereby subscriber S- 2 enters a command into either telephone 70 - 1 or telephone 70 - 2 to indicate that one or the other is designated for receiving incoming calls.
  • Another mechanism can be based on detected characteristics of a particular link between a particular telephone 70 and a particular telephone 70 .
  • each query Q can be based on determining characteristics of respective links—such characteristics can include quality of service (QoS) or financial cost of a particular link or combinations thereof.
  • QoS quality of service
  • manager 66 can elect to route call C to telephone 70 - 1 instead of telephone 70 - 2 .
  • manager 66 can also be based on presence of a particular telephone 70 . That is to say that manager 66 can elect not to even perform method 200 when only one telephone 70 is actually detected as present by manger 66 for actually receiving calls, thereby causing manager 66 to route calls C to that one telephone 70 by default.
  • manager 66 and each telephone 70 can still perform traditional call forwarding, whereby assuming that call C is initially routed to telephone 70 - 2 as a result of performance of method 200 , but there is no answer at telephone 70 - 2 , then manager 66 can be configured to route call C to telephone 70 - 1 after the attempt to route call C to telephone 70 - 2 .
  • method 200 can be performed even in the absence of an incoming call for the purposes of determining where the call should be routed when a subsequent call is received.
  • manager 66 can perform method 200 periodically, starting a step 210 , for telephones 70 and store a telephone 70 as a designated phone based on the results. The designation can be based on the result of the last performance of method 200 , or on a history of the results of several previous performances, such as an average of QoS determinations made as a result of several previous performances of method 200 . Subsequently, when a call is received for telephones 70 at manager 66 , the call can be routed to the appropriate telephone 70 based on the stored designation.
  • subscriber S- 1 can initiate the designation of a telephone 70 as the recipient of incoming calls by sending a manual instruction, through a telephone 70 , to manager 66 indicating such a designation, even in the absence of an incoming call.
  • Manager 66 can store such a designation, and use the stored designation in routing any subsequent calls received for telephones 70 .
  • a designation determined as a result of performing method 200 as a result of an incoming phone call can also be stored for future use.
  • a stored designation can serve as a backup designation in the event the performance of method 200 fails to produce a designation at the time of the reception of the call. For example, where the manager 66 does not receive a response to a query at step 215 , the stored designation can be used to route the call instead.
  • System 50 a includes many of the same components as system 50 , and like components bear like reference characters except followed by the suffix “a”.
  • a telephone 70 - 1 is omitted and telephone 70 - 2 is connected to manager 66 by both link 82 a and link 74 a .
  • the queries sent at step 210 are both sent to telephone 70 - 2 , however, one query is sent via link 82 a and the second via link 74 a .
  • Responses sent at step 215 can be sent via either link 82 a or via link 74 a .
  • Step 215 when performed on system 50 a , routes the call to telephone 70 - 2 , but sends the call via the route that is identified at step 215 .
