How do you do Voice over LTE ?
The Tin Can Telephone
- Leave it 2G (CDMA, GSM, etc.), VoLGA/UMA, VoIP – IMS, VoIP – non-IMS,
- Partnering with Over-the-top providers? VoIP SIP Trunking ?

Newer Opportunities for LTE/WiMAX and IMS
LTE/WiMAX will require regulatory features such as Legal Intercept and
Emergency Services for multimedia in both the wireless and wireline
space, along with Mobile IP solutions (Foreign Agent and Home Agent)
LTE/WiMAX will require carrier hosted solutions that promise future
convergence with VoIP, IPTV, with Presence and Location-based
services, which IMS: IP Multimedia Subsystems coupled with
applications servers can provide.
Additionally LTE/WiMAX will require the following which are provided by
applications servers:
ENUM
User authentication
Peer-to-peer video sharing
Voice call continuity to alternate access methods
Push to talk
Rich Communication Suite

Panel Questions
-What are the architecture and infrastructure choices for incumbent and
greenfield mobile operators for voice services?
-Where should service providers locate session-oriented service
delivery intelligence and control—in the core or the edge? What’s right
and wrong about each approach?
-What are the requirements for secure and interoperable wireless
services? Does IMS deliver all that's necessary? What additional issues
must be considered for FMC and blended wireless-wireline access
networks?
-What are the optimal technology choices relative to product availability,
cost, functionality and scalability in terms of performance and capacity?
