[OpenSIPS-Users] R: R: Ring Group - Memory Hunt - with serial forking?

[Mauro Davi']

Sorry,

and if I can change the qvalue with the lookup function (how with the path proposed) I cannot obtain a working sequential forking (i.e. the first call is sent to the first contact after the ring timeout the call (with the next_branch function) is forwarded to the second contact and so on...)? 

Regards,
	MD

Hi Mauro,

not really (as I understand it). What Chris wants to do is not to start 
all branches (for parallel forking) in the same time (as you do), but to 
start them one by one (ad different time intervals).

bogdan
