Hi Jeff,
are you sure your re-INVITE is going through loose_route() and attached
to the dialog context (to update it) ?
if running in debug mode, at re-INVITE time you could see a log from SST
module like "Update by a REQUEST..."
Regards,

And another issue…
With a call that went to a carrier that does support sst, I see they
refreshed the call at 15 seconds into it. Or, 15 seconds before the
session expired. You can look at it either way. They included the
following in their refresher INVITE:
Session-Expires: 90;refresher=uac
Min-SE: 90
So they've bumped the timer to 90 seconds from my 30. Cool. It seems
the sst module doesn't see this refresh, and the dialog module still
doinks the call at 30 seconds into it. Bummer. Is this normal?
On the initial INVITE I create the dialog with create_dialog() then
set the flag for the sst module.

Subject: [OpenSIPS-Users] sst module killing calls
Hello,
I'm experimenting with the sst module once again. It's configured as
follows:
modparam("dialog|sst", "timeout_avp", "$avp(s:dialog_timeout)")
modparam("sst", "sst_flag", 6)
modparam("sst", "min_se", 30)
Dialogs are set for all calls.
Calls I sent contain the following header:
Session-Expires: 30
So far, so good. When I get a 200 OK from a carrier that supports sst,
I see the following headers:
Supported: timer
Session-Expires: 30;refresher=uas
(The 30 second expiration is an experimentally low value.) When I get
a 200 OK from a carrier that doesn't support sst, I don't see those
two headers. In this case it seems the sst module still sets the
dialog expiration to 30 seconds, after which the call goes poof.
Is that correct behavior? If neither end advertise support for sst,
and neither side is going to refresh it, it seems a bit strange the
sst module would still cause the dialog to expire at the expiration time.
