[SR-Users] frequency of dispatcher probing

[Juha Heinanen]

i have defined:

modparam("dispatcher", "flags", 2)
modparam("dispatcher", "ds_ping_interval", 10)
modparam("dispatcher", "ds_probing_threshhold", 3)
modparam("dispatcher", "ds_probing_mode", 2)

and still i see that dispatcher is pinging inactive node at least 
once per second:

...

OPTIONS sip:192.98.103.3:5070 SIP/2.0.
...

what is that i'm missing in order to make ping interval 10 seconds?
