Murray will lead Manila Mavericks in Mahesh Bhupathi's league, starting November 28 in Philippines.
"Attracting new fans to the sport is important and I'm looking forward to helping take tennis somewhere new. The IPTL format is something that has never been done before and there are many different aspects that make it interesting," Murray said in an IPTL release.
Murray, who won back-to-back titles in Vienna and Valencia, gave thumbs up to the format of the league.
"The fact that every game counts toward the team score is also a great idea, you're not just playing for yourself, you have to think about your team mates as well and put them in as strong a position as possible at the end of your own set in the match," he said.

Murray's teammates would be Russian heartthrob Maria Sharapova, Jo-Wilfried Tsonga, Kirsten Flipkens, Daniel Nestor, Carlos Moya and top Philippines player Treat Huey.
Talking about his 2014 season, Murray said it has been a "tough" one.
"When I returned after my back surgery, it took much longer to get to back to full fitness than I had originally expected. It was a while until I felt like I could play at 100 per cent again. However, over the last few months I have started to feel back in that place and have had some great matches and some great results. It was great to win Shenzhen in its first ever year and I hope the Mavericks can do the same with the IPTL," he said.
