Adapter Software
The adapter runs the VxWorks™ real-time operating system. Communication
between the adapter and the Control Server is handled using media gateway control
protocol (MGCP). Voice traffic is transmitted to and from a media gateway using
real-time protocol (RTP).
After the adapter is powered on and assigned an IP address, the adapter configuration
is downloaded automatically from the Sylantro Control Server located on the service
provider network. Minimal local configuration of the adapter is required.
The adapter software has the following capabilities:
■
Automated configuration
■
Remote service and upgrade capabilities
■
MGCP compliance
■
RTP compliance
