55.3. CTI Group

55.3. CTI Group
	Chapter 55. CTI System

CTI ports, resources and other groups can be grouped to simplify the routing management; groups created can be used in the CTI Routings Table.

55.3.1. CTI Ports Group

Use the following commands to manage the CTI Groups:

a ctig id:xx [par:value] : adds a new CTI Group;
s ctig id:xx [par:value] : sets a CTI Group;
c ctig id:xx : clears a CTI Group;
d ctig : displays the CTI Group table.

The d ctig ? command shows all available parameters.

Here is an example: the G1 group contains the BRI ports (CTIP:31 and CTIP:32) towards PBX, the G2 group contains the BRI ports towards ISDN lines (CTIP:33 and CTIP:34).

	Note
	The special group `G0` is read only and it includes the resources Disa, Sip, Iax, Vo.

Meaning of the most important parameters:

S

It establishes the algorithm with which the ports listed in the group are scanned. The available values are:

R: stands for “Round-Robin” algorithm and it indicates that the scanning of the ports occurs in a circular manner, ensuring that all of them are evenly utilized;
Tip
Interesting chapter: Section 84.4.2, “How does Round Robin scanning method work in the CTI Port Group?”.
P: stands for “Priority” algorithm and it's used to indicate that the ports are scanned starting from the first to the last;
M: stands for “Multicasting” algorithm and it's used to indicate that all the port are alerted simultaneously.

R

It establishes the rule with which the CTI router will try the connection on the next port listed in the group, in the case that the connection on the previous port fails. The available values are:

ST: the next port is used only for following codes: “internal causes” (i.e. those with location=0xF0..0xFF), “0x92 no user responding”, 0xA2-0xAF, 0xC1-0xCF, 0xD1-0xDF with other locations;
IN: the next port is used only for internal causes (i.e. those with location=0xF0..0xFF);
UN: the next port is always evaluated if the previous one fails;
EU: the next port is used for any cause except 0x91 and 0x93 with any location.
Note
EU up to 8-8-6 version, worked like UN.
The name of an ICAUSE/RU/MR list between single quotes (E.g.: EU or 'my_list').

	Tip
	Interesting chapter: Chapter 93, Disconnection codes.

MC

Maximal number of simultaneous calls [1..255, MAX]

P

Enables/disables the group for call pickup; generally used for POTS ports.

P1:..P64

Input/output port/group/cluster [# or NONE, 1..600, Iax, Sip, Disa, Vo, Vm, Mix, G0..G32, PBX, cluster name or EC/RU/MR list name between single quotes] The cluster name must correspond to an existing CTI cluster. The list name must correspond to an existing EC/RU/MR list.

For every resource in the group it's possible to rewrite a series of call related parameters that actually REPLACE the corresponding fields in the routing: CDO, CGO, SDO, SGO, RGO, SP, CODERS, DJ, MJ, T301:

Special consideration for SP, CODERS, DJ, MJ:

When the group is used in POI, SR, GI they replace SP, CODERS, DJ, MJ.
When the group is used in OUT they replace SPOUT, CODERSOUT, DJOUT, MJOUT.

Each resource has a set of parameters that CAN replace corresponding fields of the routing:

If the parameter is <blank> the routing parameter is used.
If the parameter isn't <blank> the group parameter REPLACES the routing one.

	Caution
	Changes made on the CTI Groups aren't immediately active. To activate them, execute the initialization command init ctir.

55.3.1.1. POTS and CTI Group

A special group, called PBX, exists for POTS cards. See the relative section in the paragraphs below to understand how to use it.

The most important features which the CTI Group allows on CTI POTS ports are:

MULTICASTING: allows simultaneously alert to more CTI POTS ports;
PICK-UP: allows answering an incoming call on a phone, from another one connected to the same POTS card.

The configuration of these two features is made on CTI Group (as shown above).

----------------------------------+------------------------------------------------

	Note
	The special group `G0` is read only and it includes the resources Disa, Sip, Iax, Vo.

In a CTI Group, add the ports which must be alerted simultaneously and set the scanning method parameter SCAN:M, to activate Multicasting.

In a CTI Group add the ports which must support this service and set the Pick-Up parameter P:YES to activate Pick-up.

There are two methods for using the Pick-Up:

Generic call Pick-Up: allows the Pick-Up of the incoming call on all phones connected to the CTI ports that belong to the CTI group; if more than one call is coming in, the oldest one will be picked-up. The operation is:
- Pick-up the telephone handset;
- Dial “* 0” (asterisk then zero).
Specific call Pick-Up: allows the pick-up of a specific incoming call on a specific phone connected to the CTI ports that belong to the CTI group. The operation is:
- Pick-up the telephone handset;
- Dial “* 1+NUM” (asterisk, then one, then the value of the parameter NUM assigned to the corresponding CTI POTS port, i.e. *104).

	Caution
	Changes made on the CTI Groups aren't immediately active. To activate them, execute the initialization command init ctir.

55.3.2. Heterogeneous group

The CTIG now allows to use heterogeneous resources inside the group and another group too (group of groups allowed).

Any of ISDN, CTIP, VPOTS, CELL, Sip, Iax, Disa, Vo, Vm, Mix, Cluster, Cluster list (EC/RU/MR), another group (Gx), can be configured inside a group.
