[OpenSIPS-Users] trace_dialog() is missing things

[Jeff Pyle]

Hi Bogdan,

Yep, that did it.

I was working from an email on this list you had addressed to Matteo
Marzuola on 5-Mar this year at 15:26 GMT instructing him to do not define or
use trace_flag when using trace_dialog().  Unfortunately I can't find a web
link to an archived version of the message...

Anyway, all is well.  Thanks.
