[SR-Users] JsSIP:UA Request-URI does not point to us

Hello all, I am facing an issue with JsSIP not recognizing replies from Kamailio. the call sequence goes as follows: INVITE -----------------------------<-------------------------------SIP/2.0 100 Trying <-------------------------------SIP/2.0 180 Ringing <-------------------------------SIP/2.0 200 OK ACK --------------------------------<-------------------------------SIP/2.0 200 OK ACK --------------------------------<-------------------------------SIP/2.0 200 OK ACK --------------------------------<-------------------------------SIP/2.0 200 OK ACK --------------------------------<-------------------------------SIP/2.0 200 OK ACK --------------------------------<-------------------------------SIP/2.0 200 OK ACK --------------------------------<-------------------------------SIP/2.0 200 OK ACK --------------------------------<-------------------------------BYE 404 Not Found ---------------------- When JsSIP receives ACK it prints an error: JsSIP:UA Request-URI does not point to us From another thread with similar issue at https://groups.google.com/g/sip_js/c/uiaXS_qc2n8 it could be that JsSIP is not recognizing the GRUU is pointing towards it. In the INVITE message I can see a line "Record-Route: <mailto:sip:Stg-CQD0r2-10020005@erx-staging-q01.mydomain.com<mailto:sip:Stg-CQD0r2-10020005@erx-staging-q01.mydomain.com < <mailto:sip:Stg-CQD0r2-10020005@erx-staging-q01.mydomain.com<mailto:sip:Stg-CQD0r2-10020005@erx-staging-q01.mydomain.com mailto:;expires=600;received=mailto:;gr=urn:uuid:b8a691ff-f678-4866-8cf0-780d670e7e33 < <mailto:sip:9747815015@erx-staging-q01.mydomain.com<mailto:sip:Stg-CQD0r2-10020005@10.10.1.9 <mailto:sip:Stg-CQD0r2-10020005@10.10.1.9<mailto:sip:9747815015@erx-staging-q01.mydomain.com <mailto:sip:Stg-CQD0r2-10020005@10.10.1.9<mailto:sip:9747815015@erx-staging-q01.mydomain.com <mailto:sip:stg-cqd0r2-10020005@erx-staging-q01.mydomain.com <mailto:sip:Stg-CQD0r2-10020005@10.10.1.9<mailto:sip:9747815015@erx-staging-q01.mydomain.com <mailto:sip:stg-cqd0r2-10020005@erx-staging-q01.mydomain.com < mailto:sip:stg-cqd0r2-10020005@erx-staging-q01.mydomain.com <mailto:sip:9747815015@erx-staging-q01.mydomain.com<mailto:sip:Stg-CQD0r2-10020005@10.10.1.9 < mailto:sip:stg-cqd0r2-10020005@erx-staging-q01.mydomain.com <mailto:sip:9747815015@erx-staging-q01.mydomain.com<mailto:sip:Stg-CQD0r2-10020005@10.10.1.9 <mailto:sip:Stg-CQD0r2-10020005@10.10.1.9<mailto:sip:9747815015@erx-staging-q01.mydomain.com
