Phones IP Group #1 (USER). This is the alternative route if the IP-PBX does not
respond, whereby the user is searched in the device's users registration database.
8.4.10.2.1 Step 1: Enable Proxy Keep-Alive
The procedure below describes how to configure the Proxy Keep-Alive mechanism for the
hosted IP-PBX. This is done for the Proxy Set that you defined for the IP-PBX (i.e., Proxy
Set ID# 1) in ''Step 6: Define Proxy Set for WAN IP-PBX'' on page 552.
To enable proxy keep-alive mechanism:
1. Open the 'Proxy Sets Table' page (Configuration tab > VoIP menu > Control
Network submenu > Proxy Sets Table).
2. From the 'Proxy Set ID' drop-down list, select '1'. This is the Proxy Set for the IP-PBX.
