[OpenSER-Devel] Request for comment: multiple timer processes

[Bogdan-Andrei Iancu]

Hi Henning,

I'm already working on something similar (work on progress) - extend the 
module interface to fix the auxiliary  processes forking, add multiple 
timer processes, better NAT ping.

I a will try to put more on paper ;).

Regards,
bogdan
