Voice over LTE (VoLTE) is one of the most significant evolutions to have hit the voice world in many years, finally migrating one of the last bastions of traditional circuit switched calling to an IP based service. The migration is not without its issues however, requiring the deployment of a potentially complex infrastructure in the mobile network (known as IP Multimedia System or IMS) together with the skills enhancements required among the technical staff in those networks.
This joint white paper from BT and Metaswitch looks at some of the technical reasons for the delays in deploying VoLTE roaming, and addresses some core issues about complexity and how this can be simplified to smooth the path to full global VoLTE deployment and interconnectivity.
