Nokia Siemens Networks claims to have a unique way for filling the LTE voice void, and has not joined an industry initiative to create a new standard for delivering voice services over LTE, reported Unstrung. It continued: NSN stands out as the only major infrastructure supplier that is not a member of the Voice over LTE via Generic Access (VoLGA) Forum, a new group set up to write specifications for delivering circuit-switched voice and SMS services over IP-based LTE networks using the Generic Access Network (GAN) standard. NSN, instead, proposes a different approach for delivering LTE voice services, which it calls Fast Track Voice over LTE. The vendor says its mobile switching center (MSC) servers already have session initiation protocol (SIP) signaling capability, and with the Fast Track software update, those MSC servers can handle VoIP traffic in LTE networks.
