5-6 INSTALLING TELEVANTAGE
Using SIP phones with TeleVantage__________________________
TeleVantage supports VoIP desktop and softphones that conform to the Session Initiation
Protocol (SIP) standard. Developed by the Internet Engineering Task Force (IETF) specifically
for Internet use, SIP is a well-supported standard for Voice over Internet Protocol (VoIP)
communication.
Both SIP desktop and SIP softphones have been tested with TeleVantage. To use SIP phones
with TeleVantage, you must provide Dialogic VoIP resources on the TeleVantage Server that
meet the requirements in “VoIP requirements” on page 4-10.
For more information about using SIP phones with TeleVantage, see Administering
TeleVantage , Chapter 14, “Configuring Internet Telephony Support” and Appendix E, “Using
an IP Phone with TeleVantage.”
For troubleshooting tips, see Appendix H, “Troubleshooting VoIP.”
Note:
Unlike CLASS (see page 5-4) or ADSI (see page 5-3) features which take time to send to
analog phones, these features are instantaneous on SIP phones.
