[Freeswitch-users] console siptrace filtering

[David Villasmil]

Hello guys,

You can get all SIP messages coming and going to a specific profile by
typing on the console:
“sofia profile [PROFILE] siptrace on”

But if you have traffic on the box, this is a NIGHTMARE, as you get ALL
messages…

So I made a modification to mod_console.c to add a filtering for siptraces.

By enabling the filter like so:

“console filter [expression]”

Where “expression” can be anything present in the packets you want to get,
be it username, dialed number, whatever. Only those messages on which the
expression was found will be shown:

freeswitch at MacBookPro-David> console

USAGE:
--------------------------------------------------------------------------------
console help
console loglevel [[0-7] | <loglevel_string>]
console filter <filter-expression>  <<<——— NEW functionality
console colorize [on|off|toggle]
————————————————————————————————————————

freeswitch at MacBookPro-David> console filter

USAGE:
--------------------------------------------------------------------------------
console filter <filter-expression|off>

Enable, disable filtering, Only messages containing the
'filer-expression' will be printed out.
set 'filter-expression' to 'off' to stop filtering
————————————————————————————————————————

Typing:
console filter 1001

Would result in only seeing messages which include 1001

EXPRESSION (1001) FOUND IN:

My goal is to extend this to also filter other messages, like call
processing, etc. (ERR messages would not be filtered out)

I’m wondering whether it is possible to do a pull request on this?

Regards,

David
