•
External Trunk Standard Ringback (Set to “Yes”)
•
Return Disconnect Tone When Far End Party Clears (Set to “Yes”)
The Administrator should "enable" V.34 Fax Interop at V.17 speeds with SIP Gateways; the
factory default for this is disabled. This setting is a global setting; the setting is applied to all
ports on a system. This setting can be found under "Fax Advanced Settings"; for details see
the
System Administration Tool Help
for MiVoice Business.
SIP AWARE FIREWALL
To secure voice communications between public Internet and devices on the private LAN the
traffic needs to traverse corporate firewalls. Session Initiation Protocol (SIP) is typically not
supported by general purpose firewalls. Conducting voice communication sessions is a complex
task for a firewall to handle. Supporting media streams transported over separate ports
negotiated during the call setup further adds to the complexity. Transparent SIP traversal
through firewalls and NATs requires specific handling of these issues.
In general, media streams are dynamically opened on a call-by-call basis using ports within a
well-defined range. As part of SIP communication sessions RTP protocol is used to carry the
voice stream. Traditional firewalls statically open certain protocols and ports in advance. This
approach creates a security exposure when port access is not controlled by the session
signalling. Instead, a firewall that understands SIP can open up the ports for the right protocols
just when the SIP traffic needs it.
The 3300 ICP supports integration with SIP Firewalls. Mitel recommends that a SIP aware
Firewall be configured as the Outbound Proxy through the Network Elements form. Then the
SIP Peer Profiles can reference the Outbound Proxy Server and route all signalling via the
Firewall.

The ingate SIP Firewall is interoperable with the 3300 ICP based SIP solution. You can obtain
the Ingate product documentation at www.ingate.com. The Mitel SIP firewall product is the
MiVoice Border Gateway. Information is available on Mitel OnLine.
