VOIP INFORMATION
5.1 INTRODUCTION TO VOIP
TalkSwitch units can be hybrid PSTN/VoIP phone systems. The addition of
VoIP to the TalkSwitch product line adds the ability to use a broadband IP
connection for voice calls.
VoIP also enables the use of IP phones as extensions on your TalkSwitch
system. Connect an IP phone to your LAN and TalkSwitch can configure it to
have the same powerful features as regular analog phones, plus exciting
new features that break the boundaries of possibility for the office phone.
See 1.9.2.3 Connecting an IP phone on page 18 for information on
connecting IP phones.
TalkSwitch units can be used in many different applications. The most
popular VoIP configurations are multi-branch, teleworker and service
provider integration.
TalkSwitch uses the industry-standard Session Initiation Protocol (SIP) to
make and manage VoIP calls. The term SIP is often used in place of VoIP.
To connect to a VoIP network or VoIP service to make and receive SIP calls,
each location must be able to establish a high-speed connection to the
Internet or private network. The following steps should ensure success for
typical network connection methods.
