Hello, Aatif!
The fact that an user is registered, doesn't necessarily mean he should
be allowed to make a call. REGISTER messages and INVITE messages are
challenged differently, so if your gateway challenges the INVITE, you
should send the (same) credentials as for REGISTER.
In order to do that, you should use the uac_auth[1] module, that is able
to build the Credentials that your Gateway needs to present.
If for some reason your gateway does allow you to make calls without
auth after you register, than you should discuss with them the reason
why you can't do that right now. But again, that's not something common,
almost all platforms I've seen authenticate REGISTER and INVITEs
separately, with only a few exceptions.

Dear Team,
we need to used Opensips as B2BUA. With the help of *registrant* we are
able to register with Gateway and now we want the below call scenario to
achieve with B2BUA.
1) Any user(Not register with Opensip) from another IPPBX (Asterisk)
make a call to Opensips.
2) We authenticate this user as per IPPBX IP address.
3) Then we make a call to Gateway from Opensips after modifying From
User $fU, which is already register with Gateway via registrant.
4) Gateway reply back 407.
We need to resolve this 407 with authentication but we don't have any
more details how to do it with Opensips.
Thanks
