Architecture for transporting PBX signaling codes via sip
First Claim
1. A telephony communications network comprising:
- a telephony unit generating a telephony signaling code;
a translator coupled to the telephony unit, the translator encapsulating the telephony signaling code in a application layer control protocol message; and
a communications interface coupled to the translator for transmitting the message over a communications network.

Abstract
An integrated PBX and SIP telephony communications network supporting transmission of private signaling codes over SIP. A telephone emits a private signaling code for accessing a particular PBX function. An enhanced IP translator coupled to the telephone encapsulates the private signaling code within a SIP invite, request, response, information, notification message, and/or instant message. The SIP message with the encapsulated private signaling codes is transmitted over a communications network to a PBX. The PBX is also coupled to an enhanced IP translator that receives the SIP message and decapsulates the embedded private signaling codes. The codes are transmitted to the PBX for rendering a function for the telephone. A SIP user agent aware of the private signaling codes may also access functions provided by the PBX by encapsulating/decapsulating private signaling codes into/from SIP messages.

12. A telephony communications network supporting a session initiation protocol (SIP) session, the network comprising:
-
a SIP client transmitting and receiving SIP messages during the SIP session; and
a translator coupled to the SIP client, the translator configured to encapsulate and decapsulate private telephony signaling codes in and from the SIP messages for allowing the SIP client access to PBX functionality associated with the private telephony signaling codes. - View Dependent Claims (13)
