I have seen there are a couple of posts about this so I apologize if this
seems redundant.
I am starting to mess with the B2BUA and am having some issues. I am trying
to solve the transfer issue when a local OpenSIPS subcriber is on the phone
with a PSTN user and wants to transfer the PSTN user to another OpenSIPS
user. I have created the refer.xml file and set up the module parameters,
so all that is fine. The issue I am seeing are the invites getting sent out
from OpenSIPS.
If I place my
b2b_init_request("refer");
at the very beginning of my route logic before consume_credentials(),
location() and all that other junk I see that two Invites are sent
Say the user is 4...@irock.com
The B2B CALL-ID generated message gets sent to the actual IP address of
irock.com, which it shouldn't.
Then a correct invite gets sent to 4...@7x.45.x.44 which is the correct info
that is pulled from the location table, but this invite does not have the
B2B CALL-ID info in it. So it seems I have placed the b2b_init_request in
the wrong spot on my script.
Then when I place the b2b_init_request after I execute the location() in my
route logic I see the following
two invites
The first invite is the B2B invite with the B2B CALL-ID. It gets sent
correctly to 4...@7x.45.x.44 instead of to the actually IP of irock.com. The
only problem here is that within the actual TO: field of the sip message it
is 4...@7x.45.x.44 instead of 4...@irock.com. So the phone rejects this
invite with a "SIP/2.0 404 Not Found" since the phone only knows itself as
4...@irock.com.
The second invite is as usual the normal invite without the B2B CALL-ID.
So I guess the issue I am having is that dual invites are being sent and the
B2B is either sending it to the wrong IP address or it is placing the wrong
domain in the invite for the user.
