EZLoop Sip Server Solution

The EZLoop Enterprise SIP Server is a call control
server with IETF Standard Protocol SIP. This server has
the functions of a Registrar, a Proxy Server and a Call Router. It can also provide a NAT traversal when needed
in your network environment.

For the local network that EZLoop SIP Server locates, it can provide a NAT traversal service (NAT). The EZLoop SIP Server is designed to work with all sorts of SIP phones on the market and does not limit your choices by manufacturer or vendors. The IP telephony system will not only simplify your office space by combining your computer and phone on one cable, but will also provide you the flexibility to expand and grow your business.


Offers easy administration through any web browser. Remote administration is easy.

Able to make revisions even there are active sessions

Provide wide range of SIP client choices

SIP-based: Provides wide range of interoperability with SIP compliant clients, gateways,
and third-party's SIP Servers

Works flexibly with Dial Plan, NAT traversal, Authentication, and Upper/Thru Registration functions in various types of network environments.

Software Specifications

EZLoop Enterprise SIP Server will receive REGISTER requests from either a client application or UA, and update its database appropriately. Using the registrar function,
you will be able to answer calls with any client through your unique SIP-URI.

EZLoop Enterprise SIP Server will route SIP requests from clients or other servers to the most appropriate SIP-URI address based on its register database. When a user cannot be located in the database, the Dial Plan rules can be used. If the routing resolves successfully at the proxy server, a caller can establish a call even when the final SIP-URI address is unknown to the caller.

Near-End NAT Traversal
The clients behind the same NAT as EZLoop Enterprise SIP Server can talk with clients behind the NAT utilizing EZLoop Enterprise SIP Server's Near-End NAT Traversal feature.

Far-End NAT Traversal
The clients behind other NATs can communicate with the EZLoop Enterprise SIP Server over the Internet utilizing EZLoop Enterprise SIP Server's Far-End NAT Traversal feature.

Dial Plan
You can make flexible routing rules by defining matching rules and filtering rules for headers and IP addresses in the SIP packets using regular expressions in this Dial Plan.

Session Management
You can check the status or terminate the active calls.

Logs for previous sessions can be viewed through a web browser.

Operating System
Linux Red Hat v9.0 with webmin administration interface
