[OpenSIPS-Users] Dialog Replication in Active Active mode

[Jai Rangi]

Hello,

I am trying to setup two active active open-sip servers sharing the same
database. Listening on IP 192.168.1.110 (OSP1) and 192.168.1.111 (OSP2)

This is how my dialog configuration looks like.
OSP1
bin_listen = 192.168.1.110:8080
bin_children = 4
loadmodule "dialog.so"
modparam("dialog", "hash_size", 1024)
modparam("dialog", "default_timeout", 130)
modparam("dialog", "db_url", "mysql://dbuser:password@@192.168.1.2/opensips
")
modparam("dialog", "db_mode", 0)
modparam("dialog", "db_update_period", 60)
modparam("dialog", "profiles_with_value", "ib ; ob; io")
modparam("dialog", "ping_interval", 20)
modparam("dialog", "accept_replicated_dialogs", 1)
modparam("dialog", "replicate_dialogs_to", "192.168.1.111:8080")


OSP2
bin_listen = 192.168.1.111:8080
bin_children = 4
loadmodule "dialog.so"
modparam("dialog", "hash_size", 1024)
modparam("dialog", "default_timeout", 130)
modparam("dialog", "db_url", "mysql://dbuser:password@@192.168.1.2/opensips
")
modparam("dialog", "db_mode", 0)
modparam("dialog", "db_update_period", 60)
modparam("dialog", "profiles_with_value", "ib ; ob; io")
modparam("dialog", "ping_interval", 20)
modparam("dialog", "accept_replicated_dialogs", 1)
modparam("dialog", "replicate_dialogs_to", "192.168.1.110:8080")

When OSP1 get the call, it send the dialog packet to OSP2, OSP2 crashes
with this message in the logs.

I found two threads with no solutions and from the threads it looks like
dialog replication wont work in active active configuration. It required a
shared IP and will work for failover only.
I will appreciate any suggestions, or if some can share working
configuration.

Thank you,
