Configuration Notes
This section is a description of how the SIP Interop was configured. These notes should
give a guideline as to how a device can be configured in a customer environment and
how the Commend doorphone was configured in our test environment.
We recommend that the Commend doorphone is configured in Device Based mode. You
will configure the Device Based mode in the SIP Device Capabilities Form as described
in this section.
Disclaimer: Although Mitel has attempted to setup the interop testing facility as
closely as possible to a customer premise environment, implementation setup
could be different onsite. YOU MUST EXERCISE YOUR OWN DUE DILIGENCE IN
REVIEWING, planning, implementing, and testing a customer configuration.
3300 ICP Configuration Notes
The following steps show how to program a 3300 ICP to connect with the Commend
doorphone.
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
guidelines 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.
