The benefit for AtLink from the Project The modern user uses many different modes of

communications (phone, email. SMS, IM...) AtLink's EVI that automates communication process

has the need to support all these communication modes and give the power to the user to choose the preferred communication medium depending on personal needs.

AtLink's EVI currently has no support for SMS. Building and SMS module will add tremendous value to it's current offering to unostentatiously communicate between it's users.

The SMS module architectured as Web Services will allow AtLink to easily integrate the module into EVI. In addition the SMS module built to support any SMS gateway will provide AtLink the flexibility to pick the best SMS provider that make best business sense.

The prototype is built in form of Web Services. The project also require developing a Web application that use the prototype. Those Web services will later be used for EVI SMS integration.

The prototype SMS client must meet the following requirements: Support the capability to bind with any open SMS gateway

by customizing required parameters. Be able to connect to any SMTP, HTTP and SMPP SMS

gateways Be able to dynamically change the binding to any gateway

during run-time Support Two-Way SMS capabilities. Cover all SMS network in US and EU Be able to integrate with EVI Communication profiles

Conclusions

The application meets all the requirements required by AtLink Communication Inc. The SMS Spot application has been developed to

allow users to send and receive SMS messages. The application uses two SMS gateways which

are Clickatell SMS Gateway for SMTP and HTTP/HTTPS protocols and Logica simulation gateway for SMPP protocol. It has successfully sent and received the messages to and from mobile phone.

However, to deploy application, AtLink Communication Inc. needs to buy enough credit to use SMPP protocol so that the application can run with real SMPP gateway providers.
