[Freeswitch-users] Implementing emergency calls ... or call priority ?

[Shaun Stokes]

As Sebastian has pointed out you can also use limits, this will cause new calls to drop once the limit is reached but won't drop already established calls\channels. I believe the same call can be in multiple limits, if you had a limit for low priority calls you could use a LUA script to list these and drop one at random if there's a call which has higher priority such as emergency calls.

The best solution would probably be to build a LUA script.

Using LUA you can interact with FreeSWITCH via API 'api show channels as json' to list currently active channels into a JSON string, then convert that into an array. Process the array in a loop (i.e. for each or while) to identify which channels to drop based on your criteria.

Hi Peter,

You can define all sorts of limits. Have a look here: https://freeswitch.org/confluence/display/FREESWITCH/mod_dptools%3A+Limit
