Service person (e.g., realtor, plumber, painter, etc.) needs different devices for personal and business needs

Would prefer to avoid cost of carrying multiple devices for different personas

Auto-attendant selection conveyed to user so that SOHO user knows customer interest (e.g., billing, sales, scheduling, support, etc.)

Custom voice mail greetings, digital fax, call recording, call screening also available to further enhance the experience

Multi-line support (different number for each persona) provides separation of personas within the same device by allowing both personal and business lines on same phone.

Transforming LTE Architectures with SDN EPC

Mavenir’s unique architecture addresses the “data deluge problem” by handling media at the network edge

Massive data growth (video) cannot be cost effectively managed with the conventional approach of adding (many) centralized, large, high-end routers. Mavenir’s solution utilizes SDN principles to distribute the media plane (thereby localize media) and centralize the control plane as a single logical entity—an elegant software solution for ultimate scale, reliability and economy. Mavenir’s solution provides three compelling benefits:

1 Redefining LTE architectures for Voice

2 Optimized Video with Local Data Caching

3 Improved Software Performance to Lower TCO
