View source for Configuring regexp and callto parameters in cluster route module

This is an example on how to use cluster module to route the calls by setting parameters like ''regexp'' and ''callto''.

Parameter ''regexp'' which is a regular expression that describes the node name match rule.

Parameter ''callto'' is used to forward the call to the target node.

==Configuration parameters in cluster module==

In [[Clustering|clustering.conf]] file:

 [general]
 regexp=^[[:alnum:].-]\+$
 callto=sip/sip:cluster/${called}@\0.dom.ain

In the above configuration suppose that:
* We are node '''node1'''
* A call comes in for number '''87654321'''
* Routing returns '''cluster/node2/sip/sip:321@192.168.0.2;user=phone'''

The prefix equals '''cluster/''' but the node is not local. The node name '''node2''' is found matching against the regexp so the callto is evaluated by replacing parameters and matched strings.

* The call is delivered to '''sip:cluster/321@node2.dom.ain'''
* On '''node2''' the call can be routed using a [[Regular_expressions#The_regexroute_configuration_file|regular expression]] as you can see below.

==Configuration for routing the call==

In [[Regular_expressions|regexroute.conf]] file:

 [default]
 ^cluster/=${sip_x-callto};billid=${sip_x-billid}
