ZyXEL Communications ISG50 User Manual

ISG50 User’s Guide

This chapter shows you how to set up auto provisioning for the ISG50’s supported SIP clients. 

Auto provisioning allows administrators to configure VoIP related settings on snom or snom-
compatible SIP clients from a central location. You can set up and maintain a configuration file 
associated with a SIP extension on the ISG50. Auto provisioning has the VoIP devices periodically 
download the configuration file from the ISG50. 

Note: Check the documentation that came with your snom SIP client to see if it supports 

auto provisioning. 

The configuration file contains the settings you configure for a specific telephone extension in your 
organization. It also contains SIP settings necessary for the device to register with the ISG50. The 
configuration file is encrypted using 3DES (Triple Data Encryption Standard). See 

 for more information on extensions and 

 for more information on 

SIP settings. 

• Use  the  Auto Provision screens to configure auto provisioning for the ISG50’s supported SIP 

.

• Use  the  Auto Provision Advanced screen to configure the feature key settings and firmware 

upgrade URLs for the snom VoIP devices connected to the ISG50. See
