System for supporting analog telephones in an IP telephone network
View Patent ↗An integrated VoIP phone that seamlessly integrates POTS phones and IP phones is provided. In an embodiment, the integrated VoIP phone includes a Session Initiation Protocol (“SIP”) registrar, a SIP session border control (“SBC”), a SIP proxy, a SIP feature server, a SIP-PSTN gateway, a user interface and VoIP telephony functionality found in traditional VoIP phones. In an embodiment, the integrated VoIP phone includes one or more analog telephone adaptors. Other VoIP entities, such as FXS adaptors, register themselves with the integrated VoIP phone through the SIP SBC. These other entities appear as extensions on the integrated VoIP phone and the outside network will only directly communicated with the integrated VoIP phone.
1. An integrated Internet Protocol (IP) phone that couples to an analog telephone adaptor that supports one or more analog telephones such that the analog telephones function as virtual extensions of the integrated IP phone, wherein voice over Internet Protocol (VoIP) calls can be placed and received by the analog telephones and the integrated IP phone over an IP network, the integrated IP phone comprising:
a registrar that manages access signaling information and accepts registration information from the analog telephone adaptor and establishes the one or more analog telephones as extensions of the integrated IP phone;
a session border controller that controls signaling information between the IP network, the integrated IP phone and the analog telephone adaptor based on the registration information; and
a voice IP module that enables the integrated VoIP phone to place and receive VoIP calls.
2. The integrated IP phone of claim 1 , further comprising a feature server that enables enhanced features within the integrated IP phone and among the one or more analog telephones.
3. The integrated IP phone of claim 2 , wherein the integrated IP phone is configured to perform ring suppression when a user is outside a home.
4. The integrated IP phone of claim 2 , wherein the integrated IP phone is configured to allow a user to specify a distinctive ring based on an incoming call identifier.
5. The integrated IP phone of claim 2 , wherein the integrated IP phone is configured to allow a user to specify custom voicemail prompts based on an incoming call identifier.
6. The integrated IP phone of claim 2 , wherein integrated IP phone is configured to allow a user to set how incoming calls are handled based at least in part on a time of-day parameter.
7. The integrated IP phone of claim 2 , wherein an analog telephone in an analog telephone network appears on the IP network as a Session Initiation Protocol (SIP) client.
8. An integrated Internet Protocol (IP) phone that couples one or more analog telephones, wherein voice over Internet Protocol (VoIP) calls can be placed and received by the one or more analog telephones and the integrated IP phone over an IP network, the integrated IP phone comprising:
a registrar that manages access signaling information and accepts registration information from the one or more analog telephones and establishes the one or more analog telephones as extensions of the integrated IP phone;
a session border controller that controls signaling information between the IP network, the integrated IP phone and the one or more analog telephones based on the registration information;
an analog telephone adaptor that enables the one or more analog telephones to be directly coupled to the integrated IP phone such that the one or more analog telephones function as virtual extensions of the integrated IP phone; and
a voice IP module that enables integrated VoIP phone to place and receive VoIP calls.
9. The integrated IP phone of claim 8 , further comprising a feature server that enables enhanced features within the integrated IP phone and among the one or more analog telephones.
10. The integrated IP phone of claim 8 , wherein the integrated IP phone is configured to perform ring suppression when a user is outside a home.
11. The integrated IP phone of claim 8 , wherein the integrated IP phone is configured to allow a user to specify a distinctive ring based on an incoming call identifier.
12. The integrated IP phone of claim 8 , wherein the integrated IP phone is configured to allow a user to specify custom voicemail prompts based on an incoming call identifier.
13. The integrated IP phone of claim 8 , wherein integrated IP phone is configured to allow a user to set how incoming calls are handled based at least in part on a time of-day parameter.
14. The integrated IP phone of claim 8 , wherein an analog telephone in an analog telephone network appears on the IP network as a Session Initiation Protocol (SIP) client.
