ITP and SIP Connectivity
Phones using ITP mode and SIP mode allow users to communicate using the Local Area Net-
work (LAN) and the public telephone system.
IP and SIP calls can be routed through the Inter-Tel CS-5200/5400 or they can be configured as
members of the same Network Group. If the phones are configured as members of a Network
Group, they can use the Peer-to-Peer (P2P) audio feature, which is explained on
page 91 .

lowing ports and connectors may be included on your endpoint:

CAUTION
Possible Delay in Local Emergency Response to Remote Sites.
IP and SIP phone users should be alerted to the following hazardous situations:
•
If an Emergency Call phone number is dialed from an IP or SIP phone located at a
remote site that is not equipped with a correctly configured gateway, the call will be
placed from the location where system chassis is installed rather than from the location
where the emergency call is made.
In this situation, emergency responders may be dispatched to the wrong location. To
minimize the risk of remote site users misdirecting emergency responders, Inter-Tel
recommends regular testing of MGCP/SIP gateway trunk(s) for dial tone.
•
If uninterruptible power supply (UPS) protection has not been installed as part of the
Inter-Tel 5000 system, IP and SIP endpoints will not operate when electrical power fails
either at remote sites or at the main system location.
To place calls during a power failure in this situation, IP and SIP endpoint users can
only use a single line phone connected to one of the system’s power failure bypass
circuits or a local phone not connected to the system.
