Summary: dialog pvar not functional in local route

Initial Comment:
In the local route I am able to get stored dialog values using fetch_dlg_value however attempting to read value via $dlg_val I get nothing returned and error in log:

Message:
so, in local_route, if the BYE request does have a "dialog context" (the
BYE belongs to a dialog), then all dialog related information (dlg vars,
dlg flags, profiles, etc) are available without doing anything special
there.

My question was if you are sure that the BYE you are testing with belongs
to a dialog. Also, if you post your local route, it will be helpful in
troubleshooting this.

Regards,
Bogdan

Also, this is a pretty minor thing since fetct_dlg_value works and it may
have something to do with the statement from the documentation that the
pseudo variable is only available on sequential requests arter doing loose
route.  I couldn't decide if that meant it wasn't available in the local
route or not.

Okay, I've looked at the docs and what I was doing again and I still don't
understand what you are asking me.  First thing though is that I shouldn't
have used the word pvar in the summary line.

What I'm trying to do is read a dialog value via the pseudo variable
$dlg_val(name).  I can read the dialog value in the local route (BYE
initiated by dialog module timeout on the dialog) by calling the
fetch_dlg_value function but get the error when trying to read the value
directly using the pseudo variable.

Umm, I need to think about that for a while.  And go read the wiki.  I
noticed the context had been added for specifying a pvar but didn't pay
attention to it since I had set the dialog value in the INVITE and the
fetch_dlg_value worked as expected.

Let me set it back up and I'll get back to you.

Message:
there is a dialog context (and dialog vars) only for BYEs generated by
dialog module (on timeout). Is this your scenario ?
