Setting a Network Service as Default
The default Network Service is used when no Network Service is selected for the following:
●Dial out participants
●Reserving resources for participants when starting an ongoing conference
●Gateway calls
In addition, the Signaling Host IP address and the MCU Prefix in GK displayed on the Collaboration Server
Web Client main screen are taken from the default H.323 Network Service.
One IP Network Service can be defined as default for H.323 connections and another Network Service as
default for SIP connections. If the IP Network Service supports both H.323 and SIP connections, you can
set the same Network Service as default for both H.323 and SIP, or for H.323-only or for SIP-only.

To designate an IP Network Service as the default IP Network Service:

1In the Device Management pane, click IP Network Services ().
2In the Network Services list pane right-click the IP Network Service to be set as the default, and
then click Set As H.323 Default, or Set As SIP Default.
The next time you access this menu, a check mark is added next to the network service type to
indicate its selection as default.
To set this IP Network Service for both H.323 and SIP connections, repeat step 2 and select the
option you need.
