Dear Klaus,

i have the same problem when add user-privkey.pem in SIP client, I use 3CX  
soft phone.

when i run command : kamctl tls userCERT user

openssl creates three file.

INFO: Private key is locate at 
/usr/local/etc/kamailio//tls/user/user-privkey.pem
INFO: Certificate is locate at /usr/local/etc/kamailio//tls/user/user-cert.pem
INFO: CA-List is locate at /usr/local/etc/kamailio//tls/user/user-calist.pem

i copy user-privkey.pem to PC which have SIP client. after that i change the 
name to root_cert_3CXphone.pem to add to 3CX soft phone.
but problem is the same.
