Hi!
We've run into a problem when using Sofia-SIP toward OpenIMSCore. If we try to
register as a user that has a different IMPU (public identity) than IMPI
(private identity) then it seems that we need to provide an Authorization field
in the REGISTER message.
Example: If the registration message looks like this:
REGISTER sip:selinims.enea.se SIP/2.0
From: <sip:[email protected]>;tag=avUvBveQX3eUQ
To: <sip: publicidentity @selinims.enea.se>
(etc...)
We would then need to add the following field in order for the registration to
work:
Authorization: Digest
username="[email protected]",realm="selinims.enea.se",nonce="",uri="[email protected]",response=""
Otherwise OpenIMSCore will respond with a 403 Forbidden - HSS User Unknown.
Is there any way to make the Authorization field be included in the
registration request in Sofia-SIP? I thought that
NUTAG_AUTH_CACHE(nua_auth_cache_dialog) might help but it changes nothing (and
seems to be default anyway).
Perhaps this is an IMS thing - I don't exactly know which 3GPP spec. to look
at...
Best regards,
Björn Stenborg
