Project Scope :-

There was a requirement to provide phones to everyone on campus including their residence members. There were options of either expanding the existing FlexiCom 6000 system or to choose a server based solution to provide phones in colony.
Due to availability of LAN network in colony, IIT decided to take advantage of the LAN network and went ahead with a server based solution and decided to provide SIP phones to colony residents.
Initially, basic IP phones were required for their staff to communicate with other existing users. Also, a requirement for video phones arose for top faculty members, in addition to SIP clients for their mobile users. As most of the faculties are on the move, they wanted to explore SIP client technology with existing Wi-Fi network.
Seamless integration with existing users was also a primary requirement.
The Customer had tremendous trust in Tadiran and hence decided to go for Tadiran solution due to the ruggedness of the product.

Deployed Solution Benefits :-

Seamless connectivity for all users with close numbering schemes of existing 4000+ users. Feature transparency between old and new users like call back, call forward,message wait lamp etc. was the additional advantage.
IIT kept existing and previously deployed infrastructure effectively for IP phone connectivity.
Usage of existing PSTN lines for incoming and outgoing calls for new SIP phone users without spending on additional PSTN lines was achieved thanks to seamless connectivity.
Enabling mobility by usage of existing WI-FI network for SIP clients on smart phones was also achieved.
