What about interco and interop?
VoLTE introduction requires full interoperability
with the external world:
Other IMS and non-IMS VoIP domains
PSTN/PLMN
NetMatch products have been designed for smooth
all-IP transformation, allowing:
migration from TDM to IP networks
migration from 2G/3G mobile networks towards LTE
and VoLTE

Conclusions 33
LTE constitute a powerful and effective tool for overcoming the
“digital divide” in rural areas
Pre-IMS deployments can effectively accelerate VoLTE delivery
to fixed end-users, when specific features support (e.g.: PATS
requirements) is mandatory , thus enriching the SP’s offer and
providing a “zero impact” on user experience for legacy services
VoLTE architecture is perfectly suitable for exceeding the
telephony experience and delivering HD Video services across
fixed and mobile…
