[OpenSIPS-Users] Max Concurrent Calls with drouting and dialog modules

[Ali Pey]

Hi Jeff,

Thank you for the reply but unfortunately this doesn't answer my questions.
I need to bind this to the drouting module, so when I call do_routing, I
need a parameter for set_dialog_profile for whatever gateway do_routing()
picks. That was my first and second questions.

Also in your case, where do you set $var(dlgsize_out)? where do you get it
from? How would you change it? I don't want to have to change my script or
restart opensips to change this.

Regards,
Ali Pey
