Hello,
check your config operations, because the R-URI seems to be the next string (without quotes): "<BC><EA><8F>"
You can try to print $mb in such case to see the entire SIP message buffer.
Cheers, Daniel

Hello Daniel,
Thanks for the reply. Indeed there is, not sure how I managed to miss that.

Still, not sure what the problem is though...

Hello, when the ruri scheme check fails, there should be another debug message saying that. Have you pasted all log messages for the failure case?

Example from two calls from a kamailio instance acting as registrar/usrloc server, INVITE RURIs are after usrloc lookup: Call 1: INVITE sip:voip-test-gd@172.17.173.14:5063 <http://sip:voip-test-gd@172.17.173.14:5063> SIP/2.0 Call 2: INVITE sip:voip-test-user-02@10.2.24.142:32768;line=moo62e08 SIP/2.0 These INVITEs produce no complaints. Later, the same registrar produces ACKs to acknowledge 487 (thus, same transaction ACKs) responses from the next proxy in the path following a CANCEL: Call 1: ACK sip:voip-test-gd@172.17.173.14:5063 <http://sip:voip-test-gd@172.17.173.14:5063> SIP/2.0 Call 2: ACK sip:voip-test-user-02@10.2.24.142:32768;line=moo62e08 SIP/2.0 The next proxy (which produced/relayed the 487) processes the ACK for Call 1 successfully, but sanity_check at the proxy drops the request for Call 2 with: DEBUG: {1 <null> 172.30.154.189 102 ACK 08679c4228983f9e65f3b47f767b6e07@voip.domain.com <mailto:08679c4228983f9e65f3b47f767b6e07@voip.domain.com> - sanity [sanity.c:277]: check_ruri_scheme(): check_ruri_scheme entered DEBUG: {1 <null> 172.30.154.189 102 ACK 08679c4228983f9e65f3b47f767b6e07@voip.domain.com <mailto:08679c4228983f9e65f3b47f767b6e07@voip.domain.com> - sanity [sanity_mod.c:254]: w_sanity_check(): sanity checks result: 0 whereas Call 1 seems OK: DEBUG: {1 <null> 172.30.154.189 102 ACK 2a859fcc4e1c8f840191a81d7c16e76d@voip.domain.com <mailto:2a859fcc4e1c8f840191a81d7c16e76d@voip.domain.com> - sanity [sanity.c:305]: check_required_headers(): check_required_headers entered DEBUG: {1 <null> 172.30.154.189 102 ACK 2a859fcc4e1c8f840191a81d7c16e76d@voip.domain.com <mailto:2a859fcc4e1c8f840191a81d7c16e76d@voip.domain.com> - sanity [sanity.c:313]: check_required_headers(): check_required_headers passed Could this be a bug in sanity module?
