Metaswitch’s Fixed Line IMS solution enables network operators to transition fully from a fragmented circuit-switched telephony infrastructure to a single centralized all-IP voice platform primed for new revenue streams.

Traditional TDM equipment is reaching end-of-life and losing support. First generation NGN softswitches are inflexible and unable to deliver on future revenue growth opportunities. The IP Multimedia Subsystem (IMS) is the clear path forwards for network operators wanting to grow their voice business.
