Hi Again
Narrowing down the issue with dialogues disappearing.
It looks like something is not working as I expect with the session
timers.
modparam("sst", "enable_stats", 0)
modparam("sst", "min_se", 1800)
modparam("sst", "sst_flag", 6)
modparam("sst", "timeout_avp", "$avp(dlgtimeout)")
modparam("dialog", "timeout_avp", "$avp(dlgtimeout)")
modparam("dialog", "send_bye", 1)
modparam("dialog", "dlg_match_mode", 1)
modparam("dialog", "ka_timer", 0)
modparam("dialog", "ka_interval", 30 )
modparam("dialog", "enable_stats", 1 )
modparam("dialog", "detect_spirals", 1 )
modparam("dialog", "default_timeout", 43200 )
request_route {
# Initial Invite...
if ($rm == "INVITE" && !has_totag()) {
if(is_present_hf("Session-Expires")) {
$avp(dlgtimeout) = $(hdr(Session-Expires){s.int});
}
}
# handle requests within SIP dialogs
if (has_totag()) {
route(WITHINDLG);
exit;
}
}
route[WITHINDLG]
{
if (loose_route()) {
setflag(6);
dlg_manage();
route(RELAY);
exit;
}
}
From my understanding of the docs, this should extend the session timer on every
re-invite, but that does not seem to happen.
Maybe I'm confused by the flags. The sst module shows examples where both flags are
used.
modparam("dialog", "dlg_flag", 5)
modparam("sst", "sst_flag", 6)
But when reading the docs to the dialog modules, I understood that the dlg_flag is purely
optional and does not need to be set when using dlg_manage as I do. Maybe it's not
optional when using dialog AND sst together?
Also I wonder why no BYE is being sent, when the dialogue times out, despite being
configured that way.
