Matrix ETERNITY NE System Manual 209
1. You may assign a Name to the VoIP network.
Quality of Service
Quality of Service (QoS) refers to priority of IP packets on network layer. QoS is configured for both signaling (SIP)
and media (RTP). ETERNITY sends all the SIP signaling messages and the RTP packets according to the QoS
settings. To configure QoS for SIP (signaling) and RTP (media):
1. Define the priority bits for SIP messages in the field SIP Diffserve/ToS. Valid range is 00 to 63. Default:
26.
2. Define the priority bits for RTP packets in the field RTP DiffServe/ToS. Valid range is 00 to 63. Default: 46.
Disconnection on Silence Detection
You can have any matured incoming or outgoing call to be disconnected automatically, if silence (No RTP Packets)
is detected for more than a specified duration of time. To use this feature,
1. Select the check box Disconnection on Silence Detection. Default: enabled.
2. Define Detection Time (sec). This Timer defines the duration for which silence must be detected
continuously, for the system to consider it as silence detection and disconnect the call. The valid range of
this Timer is from 001 to 999 seconds. By default, it is set to 999 seconds.
3. Define the number of voice channels you would like to reserve for SIP trunk calls in the field Channel
Reservation for SIP Trunks. Default: 0.
ETERNITY NE supports 8 voice channels, which can be used by SIP Extensions and SIP trunks.
It may happen that SIP Extension users use up most of the voice channels, leaving too few or none for
making/receiving SIP Trunk calls.
This can be avoided by reserving some voice channels exclusively for SIP trunk calls.
