Hi Sammy,
OF course the replication is loop protected, otherwise it will simply
not work :). Could you share all your modparams for the dialog module ?

Hi All,
Im trying to wrap my head around a problem with OpenSIPS 3.0 dialog
profile replication. I've a cluster of OpenSIPS instances sharing
dialog profiles with each other over clusterer/binary_proto layer.
As soon as I initiate a call on first instance they all start
exchanging the dialog profiles in a never ending loop ! call needs to
drop in order for it to clear up.
What is this behavior of dialog profile replication? Is it not loop
protected ! i.e
A (send updated profile value) ---> B,C,D
B <-----recv updated profile value
C <-----recv updated profile value
D <-----recv updated profile value
B (send updated profile value) ---> A,C,D
C (send updated profile value) ---> A,B,D
D (send updated profile value) ---> A,B,C
and Loop over again!
Can anyone elaborate on this flow ! ?
Thats what I've observed from my network captures and logs. Here are
the configs for sharing profiles.
loadmodule "dialog.so"
modparam("dialog","dlg_match_mode",1)
modparam("dialog","db_mode",2)
modparam("dialog", "profiles_with_value",
"gatewayCalls;dids;userOutbound/b;userInbound/b;userTotalCalls/b")
modparam("dialog", "profile_replication_cluster", 1)
modparam("dialog", "replicate_profiles_check", 10)
modparam("dialog", "replicate_profiles_timer", 3000)
