[Serusers] Does Ser support Multi Call-Legs accounting?

[Ricardo Carvalho]

Hi all,

As seen in the following URL for OpenSer, I wonder if Ser supports Multi 
Call-Legs accounting, (feature that OpenSer already implements):

http://openser.org/docs/modules/1.1.x/acc.html#MULTI-CALL-LEGS

I have my system just already in production using Ser, but only now I 
realised that this functionality maybe lacking in Ser!... I tried to use 
the directive:

modparam("acc", "multi_leg_enabled", 1)

in my ser.cfg file, but doing so, Ser doesn't start!
Is there any other way to enable in Ser this feature? How?

Regards,
Ricardo.
