Yes for the same reasons as you mentioned, it adds dependency on external
entities in your setup and may not be suitable for any sensitive data (e.g.
related to billing etc.).
Thank you.

Why not an RR parameter? It's probably the most
reliable way to store some
dialog-persistent data, since it doesn't depend on any in-memory/runtime
state to be kept by the proxy itself, instead using the SIP messaging
itself as a persistence layer. The only trouble with this approach is that
it relies on correct RR behaviour by both endpoints and of course neither
hides the value from the endpoints not prevents them from manipulating it.
If the latter aspects are a concern, $dlg vars are probably the way to go.
If you don't want to use the dialog module, use an 'htable' with Call-ID +
From-tag as key.

Well, you can also put them in some storage backend e.g. MySQL, PGSQL
using AVPOPS or memory caches such as Redis etc.
Another way is to set it as record-route parameter using RR module. (not
recommended)

Thank you.

Thank you guys, I will try this.
I misunderstood the notion of "transaction". I was thinking that it was
the whole call-flow.

As far as i know AVPs are transaction specific only. So they will be
deleted as soon as transaction is over, i.e. 200 OK for INVITE is received
for example. They will not be available in in-dialog transactions such as
ACK, or BYE etc. What you need is to set dialog variable instead, see more
info here,

Thank you.

Hello,
I'm looking for a way to track a call by using basic AVP like this:
Into a route that treats INVITE:
$avp(s:state)="call_start";
Then, if I test this AVP into WITHINDLG route:
if($avp(s:state)!="call_start") ; the test fails.
Did I miss something?
The goal is to update this AVP during the life of the transaction.
Regards,
Igor.
