Most of international VoLTE traffic (not roaming) is still carrier via traditional interconnects.  Pure VoLTE-to-VoLTE interconnects extend the benefits of VoLTE to international calls: HD call quality and short call set-up times.  IPX providers like Digital Interconnect can help setting up SIP interworking between mobile operator networks by providing a SIP hubbing service which offers a normalization function between different implementations of the SIP standard.  It can also handle MNP and ENUM queries on behalf of the calling party network: we can discover the network owning the called party number as well as the IP address of the gateway of that network so call routing can be accomplished both at the network layer and at the service layer.   IPX 365 can also act as an ENUM proxy for inbound VoLTE traffic.  Operators are generally concerned about routing their outbound traffic. But in the world of VoLTE interworking, capturing inbound traffic also requires attention: an operator must advertise valid and correct IP addresses for its number ranges so traffic can be routed to their network. This advertisement is always a security concern and one that IPX 365 can help with.   Learn more about IPX 365.   ... View more

The bulk of mobile data traffic comes from services provided by parties like Facebook and Netflix, and these parties are Internet based.  So what is the point of carrying data roaming traffic over a highly secure private IPX or GRX network, if most of it breaks out from the home network to the Public Internet anyway?   This is a very valid point. The standards certainly allow for local break-out of traffic by the visited network.  But the implementation of local break-out has some challenges though, so for the time being mobile operators prefer the standard model.  With growing data roaming traffic volumes the picture is change and local break-out is becoming more relevant and mobile operators will need to rethink their strategy. Local break-out will require decisions like: for which roaming partners and for which and roamer applications can a data session be allowed to break out locally?   Digital Interconnect is certainly working in that direction, aiming to reshape roaming such that the GRX costs do not grow faster than the roaming revenues.   ...
