Yes, the opensips.cfg was indeed  messed up. i was tinkering with it.
Anyway, i regenerated a clean one, put in the the alias, and happily got
registrations going through. And one way audio. Except that i think am
missing the big picture.
My goal is to have Opensips front Freeswitch:

Client  <->  OpenSips  <-> Freeswitch

To act as outbound proxy at this stage. As i learn more about it, i hope to
get into NATing, loadbalancing etc. Am afraid  i have not  succeeded in
achieving this goal unfortunately, yet, though i think am very close. This
is what i have done.

1. Added the alias as advised. The registrations fail. Then when i create
 users in opensips, registration work perfectly, and one of the users can
call the other. Except that in this case it appears all is happening in
Opensips and freeswitch is not in the loop here. Infact, i verified, that
obviously registrationds are done on Opensips and not freeswitch.

2. I removed the alias, deleted the users from opensips. This time the
registrations goes through successfully onto freeswitch. Very happy, as
this is what i want. But now obviously INVITES fail with 403   Rely
forbidden.

It appears to me, there is more configuration that i must do, beyond
setting alias, to get Opensips to act as outboundproxy to freeswitch. I
need  registrations and calls to happen on Freeswitch, but via Opensips.

So after again searching the internet, i can  see that  may be something
like dynamic routing  can be done (
http://www.taitclarridge.com/techlog/2012/02/opensips-dynamic-routing.html),
or i can see whole lot of other  way of doing it (
http://www.opensips.org/Documentation/Tutorials-OpenSIPSFreeSwitchIntegration
).

What is the recommended, possibly simplest way to do this: to get opensips
proxy registrations, invites , messaging to freeswitch.

Many thanks.
