[OpenSIPS-Users] Increased macro MAX_BRANCHES and behavior of tm module

[Bogdan-Andrei Iancu]

Hi,

The 31 is a hard limit as the TM module is internally using an integer 
for storing a branch bitmask. Here is the limitation coming from. The 
change is not a trivial one, still not impossible (to drop the int 
bitmask and move to an array of int)

Regards,
