Thank you. I am reviewing the doc. I am new to Kamailio so it will take some time for
me.

I have configured Kamailio to pass a registration
request to another VoIP
provider. The reason I am doing this is to provide a sip port for users
where the ISP is blocking SIP. I am able to pass the registrations to the
VoIP provider but I'd like to have inbound calls working as well. I see the
inbound invites coming into the Kamailio server but it appears that the
server does not 'know' about the UA that is registered 'through' the
server
to the VoIP provider. Can anyone tell me how to fix this problem? Below is
my config.
You should look into the NAT handling tricks:
http://www.kamailio.org/docs/modules/stable/modules/nathelper.html#nathelpe…
and
http://kamailio.org/docs/modules/stable/modules/nathelper.html#nathelper.f.…
Take a look at the default config NATMANAGE routes and enable "natting"
for all sources except you upstream server.
Alternatively if the registrar of the voip provider supports Path,
enable that in kamailio use
http://kamailio.org/docs/modules/stable/modules/path.html#idp38122172
in the registers to add the header and set
http://kamailio.org/docs/modules/stable/modules/path.html#idp38033932
to handle the INVITEs
