Chapter 5: Call Management 5. 5.1

Overview

This chapter details the outgoing and incoming call management procedures that are performed through the screens accessible from the Call Management menu.

5.2

Call Management

The system supports call management and routing for cellular and PBX calls. It is possible to configure the system to route outgoing calls via specific cellular channels. Incoming calls are routed according to rules (CLI, MSN or B – specific) PRI channel.

3.2.1

Incoming Call from Cellular

CGW-P enables the following methods of routing incoming calls from cellular: Routing an incoming call from cellular to a specific PBX destination (see Paragraph 5.2.1.1). Routing a call from cellular to an ISDN PRI group (see Paragraph 5.2.1.2). Routing a call from according to CLI detection (see Paragraph 5.2.1.3). Intelligent MSN routing (see Paragraph 5.2.1.4).

5.2.1.1 Routing a Call from Cellular to a Specific PBX Destination To route incoming calls from cellular to a specific PBX destination, perform the steps as follows: a.

Select Call ManagementCall From Cellular. Call from Cellular screen opens (Figure 5-1).

Figure 5-1. Call from Cellular Screen b.

Select the Enable checkbox in the Cell Routing column. The fields in the cell routing column are enabled.

c.

Enter the destination phone number for routing in the Cell Routing column. An incoming call that is received on the adjacent channel will be routed to this PBX number. Figure 5-2 displays an example of settings. In this case, calls received by channels 1 to 5 will be routed to extension 1201, and calls received by channels 6 to 10 will be routed to extension 1202.

5.2.1.2 Routing a Call from Cellular to an ISDN PRI Group It is possible to route an incoming cellular call to a predefined ISDN PRI group. Incoming calls received by specific SIM cards will be routed to the ISDN channels that are contained in the group. To set up a group perform the steps as follows: a.

Select Call ManagementCall From Cellular. Call from Cellular screen opens (Figure 5-1).

b.

Click Set Groups. Groups screen opens (Figure 5-3). This screen enables to define parameters that will be implemented on all the channels associated to this group.

Select the ISDN radio button.

d.

Using the PREV or Next buttons browse to the required group. The selected group appears in the field between the buttons. The channels associated to the group appear in Selected column.

e.

Select channels in Available field in Channels area (use the Shift or Ctrl keys for multiselection). The channels are moved to Selected field. Calls will be directed to these channels.

f.

Select groups in Available field in Alternative Groups area (use the Shift or Ctrl keys for multi-selection). If the groups that were selected in Channels area are busy, calls 4

CGW-P Installation and Operation Manual will be routed to the channels in this alternative group. Make sure that the groups selected as alternative are defined. Do not select a group to be an alternative to itself (i.e. do not set Group 1 as an alternative to Group 1).

Outgoing Calls from PBX

To route outgoing cellular calls from the PBX extension to the specific cellular channel or groups of channels, select Call ManagementCall from PBX. Call from PBX screen opens (Figure 5-8).

Figure 5-8. Call from PBX Screen CGW-P enables the following methods of routing outgoing calls from PBX: Routing outgoing calls from PBX through cellular groups (see Paragraph 5.2.2.1). Routing outgoing calls using LCR tables (see Paragraph 5.2.2.2). Routing outgoing calls using white and black lists (see Paragraph 5.2.2.3).

5.2.2.1 Routing Outgoing Calls from PBX through Cellular Groups Setting the cellular groups enables to group certain channels and apply rules to this group. It is possible to route an incoming cellular call to a predefined ISDN PRI group. Incoming calls received by specific SIM cards will be routed to the ISDN channels that are contained in the group. To set up a group perform the steps as follows: a. Select Call ManagementCall From PBX. Call from PBX screen opens (Figure 5-8). b. Click Set Groups. Groups screen opens (Figure 5-9). This screen enables to define parameters that will be implemented on all the channels associated to this group.

The channels associated to the group appear in Selected column. e. Select channels in Available field in Channels area (use the Shift or Ctrl keys for multiselection). The channels are moved to Selected field. Calls will be directed to these channels. f.

Select groups in Available field in Alternative Groups area (use the Shift or Ctrl keys for multi-selection). If the groups that were selected in Channels area are busy, calls will be 10

CGW-P Installation and Operation Manual routed to the channels in this alternative group. Make sure that the groups selected as alternative are defined. Do not select a group to be an alternative to itself (i.e. do not set Group 1 as an alternative to Group 1). g. Select a mode in Channel Selection Mode. The options are: Cyclic Up – the PRI channel will be selected in ascending order and will continue from the last selected channel. Cyclic Down – the channel will be selected in descending order and will continue from the last selected channel.
