Re: [sr-dev] [kamailio/kamailio] SCSCF failing to send INVITE to application server. (Issue #3015)

We are trying to test private VoLTE setup with real UEs using open5gs EPC , kamailio IMS and application server. We see INVITE request reaching till term-SCSCF with URL (sip:405874000000955@ims.mnc874.mcc405.3gppnetwork.org;user=phone) but it is not forwarding request to application server. SCSCF is trying to fetch IMPU record for application server with tel uri even though it receives SIP uri in INVITE message. Hence fails to reach application server. Could anyone help us on why 'isc_match_filter()' function is returning tel uri even though it is receiving sip uri in message? Attaching log and pcap for reference.
