Hi, I have presence in OpenSer same box.
modparam("presence","server_address","sip:85.92.0.210")
I've a problem because I get "in-dialog" SUBSCRIBE messages without
"Route"
header:
When my SIP client (Twinkle or X-Lite) starts up it sends a SUBSCRIBE
NOT-in-dialog:

And after 60 minutes (presence refresh in X-Lite) the following SUBSCRIBE
from X-Lite is this sent. Note that:
- This is a IN-DIALOG SUBSCRIBE (has totag and same callerd ID as before).
- This in-dialog SUBSCRIBE hasn't "Route" header !!!!!!!!!!!

So, because this second SUBSCRIBE hasn't a "Route" header the
funcion "loose_route()" doesn't match it and it's routed as
NOT-in-dialog
message.
So, what to do??? I've a in-dialog message without "Route" header, so
it's not
routed by "loose_route()".
I've tryied with this:
if (loose_route() || has_totag()) {
but it generates a loop.
Does OpenSer store the SUBSCRIBE dialog info for 60 minutes? could it
recognize this establishd dialog? or should I route this in-dialog message as
NOT in-dialog?
Thanks for any explanation.
