Sampling Rate
The sampling rate is a measure of the accuracy of the audio when it is digitized. To convert analog audio
to digital, it must collect or sample the audio at specific intervals. As the rate of sampling increases, it
raises audio quality.
SBC
A Session Border Controller (SBC) is a relay device between two different networks. It can be used in
firewall/NAT traversal, protocol translations and load balancing.
Scalability
Scalability describes the ability to increase the capacity of a network device by adding another identical
device (one or more) to your existing deployment. In contrast, a non-scalable solution would require
replacing existing components to increase capacity.

SIF defines a video resolution of 352 x 240 pixels (NTSC) or 352 x 288 (PAL). This is often used in
security cameras.
Signaling
Signaling, also known as call control, sets up, manages and ends a connection or call. These messages
include the authorization to make the call, checking bandwidth, resolving endpoint addresses, and
routing the call through different servers. Signaling is transmitted via the H.225.0/Q.931 and
H.225.0/RAS protocols in H.323 calls, or by the SIP headers in SIP calls. Signaling occurs before the
control aspect of call setup.
