He previously led BT GTM's Europe, Germany and Scandinavia units, and has also served in various sales management functions across different sectors at BT.
"Having led the Europe business, I already know a lot of our customers and have had several personal interactions with many of them at different points of time.
However, in my new role I am excited to meet several new customers as well as deal with the voice customers on a global basis," said Thiel.
Thiel's main task will be to support BT's customers in addressing their challenges, particularly in their migration to IP.
