Hi,
I figured out the issue. It is Topos Module that does this problem. Without
Topos enabled everything works fine.
The Kamailio version we have on all nodes is 5.3.8 and the config for topos
is this.
modparam("topos", "db_url", DBURL)
modparam("topos", "mask_callid", 0)
modparam("topos", "sanity_checks", 0)
modparam("topos", "branch_expire", 130) # 3 Min
modparam("topos", "dialog_expire", 10800) # 3 Hours
modparam("topos", "clean_interval", 60)
modparam("topos", "event_mode", 3)
modparam("topos", "contact_host", "sip.myservice.com")
Is there something wrong in this config or it is a bug/limitation on Topos
Module?
Kind regards,
Angelo
