SIP Proxy as a CUSP Replacement
Expertflow SIP Proxy Server is fully capable of replacing Cisco CUSP in UCCE/PCCE enviornment as it has been declared End of Support. It will help enterprises in the same manner to aggregate their Session Initiation Protocol (SIP) elements into a centralized architecture to simplify and improve the flexibility of their network. An enterprise network may include Cisco Unified Communications Manager for call control, Cisco Unified Border Element for session control, and Cisco Unified Customer Voice Portal for interactive voice response as well as other Cisco and third-party SIP-based elements.
Features | Description |
|---|---|
Proxy for SIP Unified Communications signaling | Provides proxy functionality for SIP-based communication, allowing for the routing of signaling messages between different endpoints in a network. This functionality is being provided through the use of the core tm (Transaction Management) module and the dispatcher module for load balancing and routing of SIP messages to endpoints. |

Signaling Support | Supports a wide range of signaling protocols for voice. |
Address Resolution | Provides support for address resolution using DNSfor translating phone numbers into SIP addresses. |
TCP, User Datagram Protocol (UDP), and Transport Layer Security (TLS) | Supports both TCP and UDP for SIP message transport, as well as TLS for secure transport. This is provided through the use of the proto module for protocol handling and tls module for TLS support. |
Redundancy and high availability options | Provides support for redundancy and high availability through the use of load balancing and failover mechanisms. |
SIP header manipulation | Provides powerful SIP header manipulation capabilities, allowing for the modification, addition, and removal of SIP headers. This is achieved through the use of the hdr module that provides various functions for accessing, modifying, and manipulating SIP headers. |
Support for IPv4 and IPv6 | Supports both IPv4 and IPv6 network protocols for SIP communication, allowing for seamless communication between different network types. This is achieved through the use of the proto module that supports both IPv4 and IPv6 transport protocols. |
Call Admission Control | Provides support for call admission control. This allows for the control of call traffic and resource allocation. This is achieved through the use of the CAC (Call Admission Control) module that provides various functions for monitoring and controlling call traffic. |
Dynamic Call Routing and Load Balancing | Provides support for dynamic call routing and load balancing, allowing for the intelligent routing of call traffic based on various parameters such as caller ID, user location, and call quality. This is achieved through the use of the dispatcher module, which provides advanced routing and load balancing capabilities. |
QOS Support | Provides support for quality of service (QoS) through the use of differentiated services code point (DSCP) and IP precedence marking. This allows for the prioritization of SIP traffic and the allocation of network resources based on traffic priority. This is achieved through the use of the textops module, which provides functions for setting and manipulating DSCP and IP precedence values. |
Monitoring and reporting through syslog, SNMP | Provides support for monitoring and reporting through various methods such as syslog, SNMP, and SNMP traps. This allows for the monitoring of SIP traffic, call quality, and system performance. This is achieved through the use of the syslog module for logging, and the snmpstats module for SNMP support. |
