Cards

After physical configuration and installation in the machine you have to configure IPBrick. To make this step you have to know how the card was physically configured, i.e., each port configuration. After the physical installation of the hardware, you can configure cards in the IPBrick web interface in the menu:

Advanced Settings - Telephony - Cards

To insert click on Insert, and then indicate (as shown on Figure 5.38):

Figure 5.38: Telephony - Insert

Menu to insert cards:

• Type of card: Can be analogic, RDIS BRI or RDIS PRI;
• Number of ports: Number of ports in the card;
• ports configuration: Each port can be configured to connect to pre-setted interfaces: PBX or PSTN (only for RDIS BRI cards). You can configure like this:
  • NT PtP (Point to Point);
  • NT PtMP (Point to Multi-Point);
  • TE PtP (Point to Point);
  • TE PtMP (Point to Multi-Point).

If the port is connected to the landline (PSTN) you need to configure the setting as TE. If the port is connected to the PBX gateway you have to configure the PBX port and configure the setting as NT. A RDIS FAX usually behaves like a PBX requiring the port configuration as FAX (to show this option requires a FAX interface configuration) and configure the setting as NT. If there is a GSM interface configured in one of the ports you have to choose it on the list and configure the setting as TE. To configure a ISDN PRI you have to indicate if the line uses R2 protocol (protocol used in Brazil) and if the CRC4 is active on the line.

After the configuration, we can see a list with the configured cards,as visible in Figure 5.39.

It's possible to call from phones connected to landline PBX and, if IPBrick is connected to PSTN and to a PBX, you can also answer calls. IPBrick will work in a transparent mode, switching all the traffic from PBX to PSTN and vice-versa.
