[OpenSER-Users] "noisy_ctimer" parameter in TM module

Hi,

I want to get some feedback from the users regarding one of the TM 
parameters: "noisy_ctimer" .

This parameter, is disabled, would try to let a call to ring for ever 
(openser will never give internal timeout). But, the parameter is 
automatically turned on (disregarding the script setting) in certain 
conditions:
    - parallel forking is done
    - a failure route is set  
    - a failure callback is set by other module (like acc, cpl, dialog, etc)
    - a fr_invite timeout was configured via AVP
    - some reply was already received
    - no other module explicitly asked for this (like siptrace, acc,osp)

Following some discussion on the tracker, there is large support for 
removing this parameter as:
    1) it is difficult to anticipate the final behaviour due complicated 
logic
    2) due all dependencies, in 99% of the case, the param will be 
automatically turned on
    3)it breaks the RFC3261, which make mandatory to have a final reply 
form a stateful proxy

My question is:

Is anybody having a good point in not removing this parameter (and 
having noisy_ctimer behaviour all the time)?

I'm pushing this question only on users list, as between the developers, 
there is an consent in removing it ;)


Regards,
Bogdan
