[OpenSIPS-Users] 408 for non-invite request

[Bogdan-Andrei Iancu]

Hi Patrick,

First, you can control the timeout in a per-request fashion, by setting 
from script some TM variables:
     - in 1.11 - 
http://www.opensips.org/html/docs/modules/1.11.x/tm.html#id295747
     - in 1.10 - 
http://www.opensips.org/html/docs/modules/1.10.x/tm.html#id294137

And no, 4320 is not supported, I will look into it.
