tudy SIP-based ATA and VoIP Router

Solution

Customer

A leading provider of broadband communications and storage semiconductors for wireline and wireless applications

Overview

HCL offers readymade protocol stacks and test frameworks for customers. HCL also offers engineering services for porting these stacks to various OS and hardware platforms. This case study illustrates porting of HCL’s SIP stack to customer’s hardware platform, running on UCLinux, to provide the functionality of VoIP ATA and VoIp Router.

System Overview and problem Description

The customer wanted to develop reference design (to demonstrate the capability of their MIPS-based VoIp processor) of an Analog Telephony Adapter (ATA) and modify that into a VoIp Router with WLAN functionality. The design targeted OEM and ODM clients. The overall objective of this project was to develop software for ATA (Analog Telephony Adapter) and VoIP Router. VoIp Router provided the customer with benefits such as broadband Internet sharing, Firewall security, VPN connectivity, IP telephony, audio/video streaming, Wireless LAN etc.

Solution from HCL

HCL designed and developed hardware and software for the ATA and VoIP Router. The solution included right component selection, design of PCB with

multiple layers, porting of SIP and RTP stacks on to the processor board, development of applications and integration of all modules.

Accomplishments

l Hardware

Compact 4-layer design

Component selection with reduced BOM

RoHS

l Software

SIP, RTP, VPM integtration

Call process application and network management

l Prototype delivery of ATA for conference shows by the customer

l Effectively integrating various dependent modules delivered by the customer and third party

Challenges Overcome

l Compact 4-layer PCB design (to reduce cost)

l Component selection with reduced BOM

l Integration of multiple versions of OS, voice drivers and SIP Stack

Valued Delivered

l Leverage HCL’s extensive in developing VoIP solutions

l Both the hardware and software were handled by a single vendor, eliminating coordination issues with multiple vendors

l Reduced time-to-market using HCL’s SIP Stack

SIP Test Tool

CISCO“We have used HCL’s SIP test tool for protocol compliance testing of the SBC. The SIP tool covers the SIP RFCs extensively and is very flexible to use. The HCL team has helped us modify the tool to suit our needs and given us prompt response for all the support requests.”

QUALCOMM“QUALCOMM has chosen HCL’s SIP testing tool for the functional and regression testing of our SIP products. It incorporates tests drawn from various RFC’s which helped us cut down on test script development time. This is the only tool we found that supports a comprehensive list of SIP related RFC’s mandated by 3GPP/ 3GPP2. Its ease of use and wide range of APIs have helped us expand its use on our IP Multimedia Subsystem (IMS) Products.”

ERICSSON“We chose HCL Technologies SIP protocol test tool to be used when testing our SIP product. The tool has a good test suite and the flexibility to design own test cases which helps us to save time and costs”.

PMC“Selecting a partner for the development of PMC–Sierra’s analog telephone adapter and VoIP Router reference designs were an important decision. HCL Technologies has the market experience and ability to deliver high quality products, and the willingness to respond to our customers requirements on a timely basis”.
