Hi guys, Kamailio P-CSCF is unable to return true for: pcscf_is_registered("location") on INVITE and responds to the INVITE with: 403 Forbidden - You must register first with a S-CSCF Registration completes fine and I can see database with valid location entries though... Any ideas? Regards, Owais -- View this message in context: http://sip-router.1086192.n5.nabble.com/Kamailio-P-CSCF-error-on-INVITE-tp1… Sent from the Users mailing list archive at Nabble.com.
