7.2 STARTING AND CONFIGURING THE i220 SIP SET
7.2.1 PBX Pré-requisites
Following actions must be carried out on the Call Manager:
• Activation of Windows feature: "Call Server SIP Gateway (GSI)".
• Déclaration of IP equipmetns in the Call Manager.
• For more details, see NeXspan Communication Server - Installation and Configuration Guide
(section 1.6.2).
7.2.2 Sets time stamping function
Used a time stamping service to synchronise the i220 SIP set time and date with an other i220 SIP
set.
This service can be:
• An external NTP server. The sets are in the external server that provide the clock (see web site:
http://www.cru.fr/NTP/serveurs_francais.html .
• A Windows domain controller: service W32Time to be enabled ( http://support.microsoft.com/
default.aspx?scid=kb;fr;816042#9 ). The sets are in this controller (itself synchronised locally or
remotely…).
• An internal Company time server on which are all the sets (a service of host PC, a router, a
hardware basis,…).
• For example, you can install the shareware software atcs22.exe Absolute Time Server ( http://
www.timeutilites.com/ ) on the PC hosting the Call Manager. Run the downloaded file, then
reboot the PC. Next, check that Windows service is started.
7.2.3 Manual configuration of sets
i220 setting up is composed of the following steps:
• configuration of i220 SIP set,
• update of the i220 SIP set software by Web interface,
• check the status of the subscribers on the PBX side.
In the following procedure, this configuration is used as an example:
• Call Server IP address: IP 10.3.2.99 / 24,
• NeXspan Communication Server hosts the Call Manager, the SIP proxy or GSI gateway, DNS
ans SNTP server,
• i220 SIP set with a 7500 directory number and the following IP address: 10.3.2.57 / 24,
• the LAN has no Default Gateway (= 0.0.0.0).
