Panel Discussion

NIMS is a project to modernise Deutsche Telekom's IMS service and deliver a foundation for its digital transformation – to support its 18 million fixed line voice customers. As part of our in-depth NIMS coverage, we have held two roundtable discussions and produced a series of interviews. Now though, it’s the chance for our audience to participate, as we invite back our guests to answer questions in our live Q&A show.
