javascript info

Ex output:

javascript info
nip = ./share/scripts/nip.js
sip/74: ReRoute

nip.js is a global script and sip/74 is a sip channel that is assisted by the configured routing script

Reload scripts

You can use this to reload a script after you have modified it.

javascript reload script_name

Evaluate expresion

Ask Javascript interpretor to evaluate expresion:

javascript eval Engine.debug("test")

Ask Javascript interpretor to evaluate expresion in the context of a specific script. In this case you will be able to access global variables from that script.

javascript eval=script_name Engine.debug("test"+var_name)

Ask Javascript interpretor to evaluate expresion in the context of a specific routing script instance. In this case you will be able to access global variables from that script instance.

javascript eval=chan_id Engine.debug("test"+var_name)


javascript eval=sip/74 Engine.debug("test"+var_name)

You can use the eval functionality to test javascript expressions and in some cases it's very useful when debugging.

Inspecting variables

Inspect variable in running script:

javascript eval=script_name Engine.print_r(var_name)

View Object or Array in JSON format:

javascript eval=script_name JSON.stringify(var_name,null,2)

See installed message handlers

You can use even use eval to see installed handlers for a script. This help a lot to debug scripts especially when you include functionality from multiple files.


   javascript eval=roaming Engine.print_t(Message.handlers())

Example output:

   name              priority handler        trackName     filterName filterValue
