I haven't explicitly disabled this in the script. I'm using a script
built on the standard residential script... by now it's moderately
The 30 second timeout was because of create_dialog("PpB") and the pings
were not being sent out the correct socket so it wasn't receiving
replies and OpenSips was killing the call from the middle. (I have
packet traces and logs that show this).
The only parameter I have for rr module is
modparam("rr", "append_fromtag", 0)
which I believe was put there by the template as I have no idea what it
means and so I wouldn't have put it there myself.
I do see two record route headers in one example sip-trace that I just
looked at. The outgoing call is heading from asterisk via ipv6 to the
proxy and then via ipv4 to the sip trunk... record route headers look like
Showing that indeed Opensips has recorded itself twice in the route.
Thanks for taking some time with this!
