El feminismo y su diversidad de perspectivas

With SIP authentication (Configuration > Resources > IP Trunks > SIP Trunking > Private > Authentication), the BCM can challenge incoming calls and authenticate itself to remote servers that request authentication to ensure callers are authorized to place calls to the local system.

SIP calls are not authenticated based on individual calls. If SIP authentication is on, the system authenticates all SIP calls. If SIP authentication is off, the system does not authenticate SIP calls.

The following table describes the SIP Authentication fields. For the corresponding procedures, see Configuring SIP authentication (page 310) and Configuring SIP authentication for a SIP user account (page 311).

IP (VoIP) trunk configuration

H.323 trunks

To configure an H.323 IP trunk, you need to configure the route and specify the H.323 settings and media parameters. You also need to configure the options common to all IP trunks (Options common to all IP trunks (page 99)).

To find the H.323 trunk configuration panels in Business Element Manager, navigate to Configuration > Resources > IP Trunks > H323 Trunking. There are three tabs under the H323 Trunking tab: Routing Table, Settings, and Media Parameters. The

configuration parameters for each of these are described below.

H.323 routing table

The BCM routes calls directly from entries in the routing table (Configuration > Resources > IP Trunks > H323 Trunking > Routing Table) or uses the services of a gatekeeper if one is configured. To add a route, you click the Add button at the bottom of the routing table and then complete the fields of the Add Remote Gateway panel. To delete a route, you select the route and click the Delete button. The parameters of the Add Remote Gateway panel are described below. For the corresponding procedure, see Configuring an H.323 route (page 314).
