the Thrane IP Handset.
To change the Thrane IP Handset compatibility, do as follows:
1. Select Settings > IP handsets > Server settings.
2. Select the Thrane IP Handset compatibility as follows:
• If you are connecting your Thrane IP Handset(s) through a separate router with NAT, select
Version 1.8 or newer and use Thrane IP Handsets with software version 1.8 or newer.
• If you are connecting your Thrane IP Handset(s) directly to the terminal or through a switch
without NAT, select Version 1.7 or older. In this case you can use Thrane IP Handsets with
any software version.
