[OpenSIPS-Users] Store values of the REGISTER and Retrieve them in the INVITE

[Nick Altmann]

Don't look into my 1-st answer, it's erroneous.

Try to change
if (t_check_status("200")) {
to
if ((is_method("REGISTER")) && (t_check_status("200"))) {

in onreply_route[2]. Maybe variable in your cache was rewritten by 200 OK
reply from another request? (depends on your configuration).
