IP Trunk - (SIP) Session Initiation Protocol
Description
The SL2100 IP Trunk SIP package sends the real time voice over the corporate LAN or WAN. The
voice from the telephone is digitized and then put into frames to be sent over a network using Internet
protocol.
Using VoIPDB equipment at a gateway (a network point that acts as an entrance to another network),
the packetized voice transmissions from users in the company are received and routed to other parts
of the company Intranet (local area or wide area network) or they can be sent over the Internet using
CO lines to another gateway.
Depending on the requirements and resource allocation in the LAN/WAN/Internet, the VoIPDB - SIP
can be configured to use any of the following voice compressions:
• G.711 A-law - Highest Bandwidth
• G.729 (a) - Most often used
• The LAN/WAN or Internet connection is provided by a 10 Base-T/100 Base-TX Ethernet.
The SL2100 supports a maximum of six SIP Profiles allowing you to connect to a multiple of SIP
Carriers and have different SIP System Interconnections at the same time.
Support 6 SIP profiles on SL2100 system.

VAD Enhancement
RTP voice data always transmitted during VoIP talking even if a user is not speaking. If VAD (Voice
activity Detection) is enabled in a system, the system can stop sending RTP voice data while a user is
not speaking.
This enhancement improves this VAD determination method by using SIP negotiation.
