[OpenSIPS-Users] rtpengine (setid_avp) issue with BYE and CANCEL

[Răzvan Crainea]

Hi, Mickael!

AVPs are only available during transaction - initial request and its 
replies, but it is not avaialble to sequential requests (such as CANCEL 
or BYE). If you want to store a value throughout the entire dialog, you 
should save the variable in a dialog variable[1], something like this:

# initial INVITE
$avp(setid) = 1;
create_dialog();
$dlg_val(setid) = $avp(setid);

# CANCEL or BYE, *after* loose_route() is called
# so that the dialog is matched/found
loose_route();
$avp(setid) = $dlg_val(setid);

Hope this helps.

Best regards,
Răzvan
