SIP CODEC Tunneling for Contact Center Status Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for transferring status information and control signals between distributed contact center sites are inefficient, often requiring insecure broadcasts or complex configurations, which pose security risks and are impractical over the public Internet.
Innovation Solution
The use of Real-time Transport Protocol (RTP) to transfer status information and control signals between endpoints, allowing for secure and reliable communication by inserting data into RTP headers, payloads, or trailers, and employing Session Initiation Protocol (SIP) for secure setup and encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preconfigured sockets or broadcasts are used to transfer status information between sites, then data transmission can be established, but security risks increase and firewall compatibility decreases
Solution Approach 1:
The patent uses SIP (Session Initiation Protocol) as an intermediary to establish secure communication channels between distributed contact center sites. SIP acts as a mediator that negotiates security parameters, establishes encrypted sessions, and manages authentication, thereby enabling reliable data transmission while mitigating security risks through standardized security mechanisms.
2Productivity
If preconfigured sockets are used for communication, then direct data transfer is possible, but configuration complexity increases due to discovery mechanisms and firewall requirements
Solution Approach 1:
The patent leverages the universality of SIP protocol, which is already widely deployed in VoIP and communication systems. By using SIP's existing authentication, encryption, and session management capabilities, the system achieves secure communication without requiring site-specific discovery mechanisms or complex firewall configurations, thereby maintaining communication efficiency while reducing configuration complexity.
3Ease of operation
If broadcast mechanisms are used for data transfer, then no discovery mechanism is required, but network security is compromised and data integrity cannot be guaranteed
Solution Approach 1:
SIP serves as an intermediary that replaces the need for broadcast mechanisms while maintaining setup simplicity. SIP's standardized session establishment process provides automatic peer identification and connection setup without requiring manual discovery mechanisms, while simultaneously ensuring data integrity through authenticated communication channels and encrypted data transfer.
4Object-affected harmful factors
If HTTP/SOAP protocols are used for communication, then firewall compatibility is improved, but communication efficiency decreases due to text-based protocol overhead
Solution Approach 1:
The patent changes the protocol parameter from text-based HTTP/SOAP to binary-based SIP/RTP. This parameter change maintains firewall compatibility because SIP is a standardized protocol that firewalls are configured to allow, while simultaneously improving communication efficiency by using binary format which reduces overhead and enables faster processing compared to text-based protocols.
Data Source
AI summary
A distributed contact center and method of managing data transfers between the distributed parts of the contact center is provided. Distributed parts of the contact center are joined together through a known communications initiation protocol such as SIP, then status information and/or control signals are transferred between the distributed parts using lossless communication protocols.
