Summit Tech offers modular building
blocks to create IMS Rich Communications
Suite (RCS, RCS-e) clients designed and
tailored for your network.
The modules can integrate with an existing
IMS stack or can be adapted to integrate
with clients provided by carriers and
OEMs. In addition, Summit's enhanced
user-experience (UX) framework and service
configuration tool provide OEMs and vendors
the ability to create a unique service flow
resulting in clients ranging from RCS, RCS-e
to VoLTE (IR.92) and 2-way video calling solutions.
|
Fully customized solutions differentiating a network's capabilities can be achieved by implementing selected
modules with either currently available
IMS stacks or with our full-featured
and cross-platform RCS IMS stack, available
for Android, Windows, iOS, OSX, Linux,
Symbian, Bada and Adobe Flash. |

Web
Breakout and Over-The-Top/Legacy Device
Support
To ensure RCS & RCSE clients have
the widest possible reach, Summit offers
an innovative IMS to web/legacy gateway.
The CORG application server enables
RCS clients to share enhanced communication
with both web users and legacy devices.
|
- For web endpoints (PC, Mac &
Linux) signaling and traffic is
encapsulated using the RTMP and
HTTP-based RTMPT protocol supported
by the Adobe Flash player
- GSMA IR.84 support for legacy
handsets is accomplished via RTSP/RTP
re-encapsulation
- Mobile to web call bandwidth
is managed through CORG at both
endpoints to ensure best possible
quality
