When I load a page with SIPml-api and run some php with 'kamctl add $username' command, the sip user is created by the SIPml-api. (user created permanently inside the DB) When I load the same page with 'kamctl *ul* add <username> <uri> <expires> <path> ' command, the sip user is Not created by the SIPml-api, but rather, it is being created by Kamailio mi (user created temporarily in the usrloc table - memory). Any idea why? What is the difference between kamctl add & kamctl *ul* add with regard to SIPml-api? kamctl ul show: 1. created with kamctl add (created actually by SIPml) AOR:: buyer_1455193937827 Contact:: sips:buyer_1455193937827@df7jal23ls0d.invalid;rtcweb-breaker=no;transport=wss Q= Expires:: 32048 Callid:: 906095b6-2c0b-d32a-a53b-3849c9283373 Cseq:: 32534 User-agent:: n/a Path:: <sip:+5m6nQWEplAJygbAYyAyE8W8eJ1U490=@192.99.32.50;lr;ob> State:: CS_NEW Flags:: 0 Cflag:: 0 Socket:: udp:192.99.32.50:5060 Methods:: 4294967295 Ruid:: uloc-56bb4c0c-14d5-c2 Reg-Id:: 0 Last-Keepalive:: 1455193940 Last-Modified:: 1455193940 2. created with kamctl ul add (and ignored by SIPml client) AOR:: buyer_1455198121667 Contact:: sips:buyer_1455198121667@commodisee.com Q=1 Expires:: 893 Callid:: 3OaR3wW1zSn5qHzPFLB(a)kamailio.mi Cseq:: 34 User-agent:: SIP Router MI Server Path:: <sip:buyer_1455198121667=@192.99.32.50;lr;ob> State:: CS_NEW Flags:: 0 Cflag:: 0 Methods:: 4294967295 Ruid:: ulcx-56bb4c0c-14e9-22 Reg-Id:: 0 Last-Keepalive:: 0 Last-Modified:: 0
