[SR-Users] Problemas with kamctl ul show - Kamailio 4.1

Hello, I'm having a problem with the command kamctl ul show, and I do not understand what is happening. On my server when I run just "kamctl ul show" command works fine but when I run "kamctl ul show [<username>]" an error happens. Before when I was using Kamailio 3.1, its work ok. I looked for some documentation and found nothing about this. For example: *$ /home2/local/kamailio/sbin/kamctl ul show* Domain:: location table=512 records=1 max_slot=1 AOR:: 2501 Contact:: sip:2501@192.168.XXX.XXX:5060;transport=udp Q= Expires:: 3594 ... Domain:: aliases table=512 records=0 max_slot=0 *$ /home2/local/kamailio/sbin/kamctl ul show 2501* 404 AOR not found Thanks for Help. Best regards. Raphael
