Making VoLTE Interconnect Work

1,338 views

Published on

A webinar session helping mobile operators understand the following concepts:
• What is the difference between VoLTE interconnect and roaming?
• What are the critical steps and components necessary to successfully implement a VoLTE interconnect solution?

• How do Electronic Number Mapping (ENUM), session and policy control, and interworking impact VoLTE interconnect?

• What are other interconnect services – such as ViLTE, SMS-over IP (SMSoIP) and Rich Communications Services (RCS), including Wi-Fi calling – that mobile providers can implement using the IMS framework needed for VoLTE?
