Electra Elite IPK II Document Revision 1
IP Station (MEGACO) - MG 16 2 - 471
In voice communication, particularly Internet telephony, the Mean Opinion Score (MOS) provides a
numerical measure of the quality of human speech at the circuit destination. The scheme uses
subjective tests (opinionated scores) that are mathematically averaged to obtain a quantitative indicator
of the system performance. The maximum MOS is 5.0.
This interface supports via KSU configuration:
J
MEGACO (H.248) signaling Protocol
J
DTMF generation
J
RTP port number designation
J
TOS field QoS support
J
Tone generation
J
General Tone detection
J
G.711 and G.729a voice compression
J
10/100 Base-T LAN interface
J
Echo Canceller
Conditions
Group listening is not supported by (MEGACO) IP stations.
Station Relocation is not supported by (MEGACO) IP stations or IPK Soft Phones.
Not all data networks are suitable to support Voice over Internet Protocol (VoIP). A good
VoIP network solution requires low-latency, low jitter, and low packet loss. Accordingly, the
network must be evaluated for these factors to determine whether or not it can provide toll-
quality speech paths.
When 6- or 7-digit station numbers are used, this feature is not available.
Night Mode is indicated as N on an IPK Soft Phone.
Default Setting
None
