Developed by mobile connectivity software vendor iPass in conjunction with Telstra's Innovation Centre, the Telstra Remote Working solution allows single sign-on across fixed-line and wireless networks.

Telstra managing director of convergent solutions, Lynda O'Grady, said so far it has had "phenomenal" feedback from large enterprises, including the NAB. O'Grady claimed the bank has successfully completed a proof-of-concept and will deploy the solution to its road warriors in the future.

"The companies have been coming to us because the solution was needed," O'Grady said, adding Telstra is developing a tailored solution for large enterprises in addition to an "off the shelf" version, which is due mid 2006.

About 30 organizations are "almost pushing" the solution, which "was needed for some considerable time", into their enterprises, she said.

NAB spokesperson Megan Lane confirmed some 400 employees of the bank are doing a proof-of-concept with the solution, but stressed "no decision has been made as to whether the bank will go ahead with the concept on a larger scale".
