3300 Setup Notes

The following steps sho w h ow to program a 3300 ICP to connect with the Cyberdata VOIP Indoor Paging
Speaker SIP device.

Network Requirements

• There must be adequate bandwidth to support the voice over IP. As a guide, the Ethernet
bandwidth is approx 85 Kb/s per G.711 voice session and 29 Kb/s per G.729 voice session
(assumes 20ms packetization). As an example, for 20 simultaneous SIP sessions, the Ethernet
bandwidth consumption will be approx 1.7 Mb/s for G.711 and 0.6Mb/s. Almost all Enterprise
LAN networks can support this level of traffic without any special engineering. Please refer to the
3300 Engineering guideli nes for further information.
• For high quality voice, the network connectivity must support a voice-quality grade of service
(packet loss <1%, jitter < 30ms, one-way delay < 80ms).

Assumptions for the 3300 ICP programming

• The SIP signaling connection uses UDP on Port 5060.
