example 1

[0040] 200 OK

[0041] CSeq: 1 REGISTER

[0042] X-multimedia-service-enabled: CW=yes, CCW=yes, CND=no,

[0043] DVC=WD6035, SP=SPT

[0044] Example 1 is a message sent from a SIP proxy server (as a registrar) notifying that the account is only subscribed to Call Waiting (CW) and Canceled Call Waiting (CCW) services, but not to Calling Number Delivery (CND) Serve. The emulated device is a Kyocera 6035 phone (DVC=WD6035) and the service should follow Sprint usage (SP=SPT). After receiving a "200OK" to this header field in a REGISTER message, a SIP phone should stop displaying the calling number to the user for the entire registration period, even if such functionality is already built into the phone. The client device will use a Sprint Kyocera 6035 device with key mapping, as the phone feature uses these keys for Sprint-flavored features.

example 2

[0046] INVITE customer@x.com SIP / 2.0

[0047] X-multimedia-service-enabled: CW=no, DVC=SEI202, SP=VRZN

[0048] Example 2 shows a header field that, when present in an INVITE message or a response to an INVITE message, may be sent to an endpoint on a per-call basis. Messages are sent from the SIP proxy server to the called party terminal device. For this incoming call, the header field indicates that call waiting service should not be provided, even if the user has subscribed to the service. This is useful when the calling party does not want their call to be held on hold. After receiving this header field in the incoming INVITE message, the SIP phone shall treat the incoming call as if the called party does not have the call waiting function. Also, the end-device mapping should be that of a Siemens SNO202SIP phone, where the user's profile representation is displayed at the called party site, and the service should be mapped for use as a Verison feature.

Abstract

The invention discloses a method for remote service forwarding (RSF) between dissimilar systems with operator, service and location portability. A remote service forwarding (RSF) system allows the telephone service user to access the subscribed services via different access devices without the loss of service. The system allows a user to access different systems or uses dissimilar phone devices ordifferent service providers by porting services over an IP connection. The user may access subscribed services such as Centrex or PBX services over a mobile IP connection.

Description

[0001] This application claims priority to US Provisional Patent Application No. 60 / 527,361, filed December 5, 2003, the contents of which are hereby incorporated by reference. technical field [0002] This invention relates to digital telephones. More specifically, the present invention relates to mobile switching centers, IP phones, hosted PBX (hosted PBX) and enterprise PHS networks. Background technique [0003] In one known Remote Call Forwarding (RCF) solution, a user call has been forwarded to a telephone number at a new location, said forwarding being unknown to the calling party. When the subscriber's originating local exchange sends a signaling message to the apparent terminating local exchange, the originating local exchange parks the call. When a signaling message arrives at the original terminating local switch via the CCS7 network, the switch polls the subscriber line to determine its status (eg, whether the subscriber line is available, busy or forwarded).
