Routing

Yate has multiple routing modules. A routing module is a module that handles (sees) the call.route message.

You can set all routing in a single module or use a combination of modules. If more than one module is used, then the priority that is set in each configuration file determines the order of the modules processing the message. A numerically lower priority means a higher priority of the route. A module can add/modify parameters without handling the message.

This is the list of the routing modules and a How To's for each of them:

Routing modules in Yate	How to do routing in Yate
Regfile module	How to register users from regfile
Regular expressions module	Redirecting Calls to another User in the Regex Module
Javascript routing module	How to do routing using javascript
Register module	How to register users from register
Call forker module	How to do round-robin routing
ENUM route module
Cluster route module	Configuring regexp and callto parameters in cluster route module
Late routing Module	Forking a call using lateroute

forking the call to several numbers regexroute.conf holds:

[default]
^100$=fork lateroute/201 | lateroute/202 | sip/sip:\0@my.gateway

The call will first attempt to reach the 201 number through whatever routing possible - usually some form of registration. Then it will repeat for number 202 and only finally it will be directed to 100 at the gateway. Exact route and parameters for 201 and 202 don't have to be known in advance
