[SR-Users] Problem with locally generated BYE in dialog timeout.

[Julia Boudniatsky]

Storing the values in dialog module doesn't help.

I updated headers in event_route[tm:local-request]  by subst_hf  with saved
dialog variables (uac_replace_to/from has been used in branch route).
Now it's working.
Great! Thank you,
Julia
