Disabling Incoming Calls - Avaya XT Series Deployment Manual

Disabling Incoming Calls

About this task
You can disable incoming SIP or H.323 calls on GLAN1, GLAN2, or both network interfaces. This
is useful if, for example, you want to disable incoming calls on a public network while allowing
incoming calls coming from your intranet or company network.
Procedure
1. Access the general call settings. From the XT Series web interface, select Administrator
Settings > Protocols > General. From the endpoint's main menu, select Configure >
Advanced > Protocols > General.
2. Choose from the following options:
• To reject SIP incoming calls, select GLAN1, GLAN2, or GLAN1&GLAN2 from the
Reject SIP Incoming Calls menu, depending on the network interface you want to
disable.
• To reject H.323 incoming calls, select GLAN1, GLAN2, or GLAN1&GLAN2 from the
Reject H.323 Incoming Calls menu, depending on the network interface you want to
disable.
Note:
GLAN2 may be missing in some XT Series products. It requires an optional license.
When a protocol, SIP or H.323, is disabled, incoming calls using that protocol are
automatically rejected.
If a VLAN is active on a GLAN, all incoming calls coming from the VLAN will be
disabled as well.
3. From the web interface only, select Save.
