Hi Adbul

Thanks, I am glad the information is useful.

Do you have any thoughts on what I could I try next to get that $dlg(start_ts)
value populated in the dialog as it is still not working about adding the
loose_route() function?

I also tried looking at the logs for any reference to dialog -- tail -f
/var/log/syslog | grep dialog

The only thing that came up with rtpengine talking about dialogs so no
clues there.

Thanks to you guys for the help.

All the best.

Will
