[asterisk-dev] ast_safe_system() from within chan_sip.c

[Jaco Kroon]

Hi,

And please keep in mind that SIP calls (in asterisk 11 at least) are
very much serialized and you're going to affect the response times to
SIP frames by introducing extra work there - really do look at the ASF.

Frankly, if you're after what I think you're after, I've been parsing
the logs for exactly that since before ASF ... and I should probably
convert, but for now the tail -F ... | sed -nre '...' | banscript is
working quite nicely.

Kind Regards,
Jaco
