Hello,
are you looking for Kamailio to send re-INVITEs? If yes, that is not
available as a feature of dialog module.
Cheers,

Hi,
I am fairly new to Kamailio and had a question regarding how to use
Kamailio to enable Session refresh functionality when Kamailio is
acting as Sip Stateful Proxy.
Kamailio Version used: *5.3.2* with *Call Load based routing* using
the *dispatcher *module.
* From what i understand from the documentation, Kamailio will
probably not be acting as a session refresher, but Kamailio can tear
down the call in case session refresh is negotiated, between the
caller and the callee(via Kamailio Sip Proxy), and no message
exchange happens in the duration set in Session-Expires header. *Is my
understanding correct?*
*
*
** *I believe the above functionality is possible by using the *sst*
and *dialog* module. I have set the same according to the
documentation but I keep getting the following error:
"dialog [dlg_handlers.c:681]: *get_dlg_timeout(): invalid AVP value,
using default timeout*"
Can someone share a working example?
* When i tried hardcoding the timeout value by setting the timeout_avp
to a specific value, Kamailio did sense a timeout and hence sent a BYE
towards the caller and the Callee side both(which is what the
requirement is), however, i do see the *dialog is still not cleared*
in the "kamcmd dispatcher.list". Output excerpt below for reference:
[root@CPaaSVM ~]# kamcmd dispatcher.list
{
NRSETS: 1
RECORDS: {
SET: {
ID: 1
TARGETS: {
DEST: {
URI:
sip:172.27.44.121:5080;transport=tcp
FLAGS: AP
PRIORITY: 0
ATTRS: {
BODY:
duid=sample-cas;maxload=1000
DUID: sample-cas
MAXLOAD: 1000
WEIGHT: 0
RWEIGHT: 0
SOCKET:
}
LATENCY: {
AVG: 111.304000
STD: 1042.193000
EST: 2.385000
MAX: 9999
TIMEOUT: 1
}
RUNTIME: {
DLGLOAD: *1*
}
}
}
}
}
}
It is noteworthy that in case the BYE is initiated by either the
caller or the callee, the dialog is cleared properly and the DLGLOAD
is set to 0 on call termination.
Any pointers for the above questions would be highly appreciated.
Regards,
Harneet
