Bogdan,
Thanks for the response. I figured out my issue. Boils down to the fact
that I'm an idiot. If you don't have machines on the network up and
running when dispatcher tries to dispatch a request, subsequent INVITES
will not go out. When building out my setup, I was building each piece
and testing before moving on so I didn't have machines on the IPs
declared in the dispatcher.list yet. Now that I do have machines there,
I get INVITES 100% of the time.
My next step is to set up failure routes for when the forward doesn't
actually happen.
Thanks to all who have assisted.

Hi Anders,
according to the openser output, the request is forwarded. I also see
no errors indicating that the send failed.
Are you sure is not an issue with your network configuration? routes?
interfaces? filters?
regards,
bogdan

I'm seeing the R-URI properly set 100% of the
time. I still only get
an outgoing INVITE about 10% of the time, and always to the same IP.
(10.1.50.36)
What has to happen to get OpenSER to fire off an outgoing INVITE for
every incoming INVITE?
In the example below, R-URI is set properly to
sip:+18666775910@10.1.50.37:5060 but still no outgoing INVITE...
thoughts?
Thanks.
