[Spce-user] best practice - connecting pbx

[Marek Červenka]

hi,

i'm trying configure sipwise as  sip trunk provider for asterisk pbx

asterisk is on public ip. register to sipwise is working
i have problem with outbound calls. ngcp-proxy again and again sending 
sip 487 . asterisk for 3 times sending invite with correct auth

subscriber settings:
allowed_clis: *
trusted_source: ip of asterisk pbx
allow_out_foreign_domain: true
allowed_ips: ip of asterisk pbx

where can i find reason why proxy doesnt accept auth? 
/var/log/ngcp/kamailio-proxy.log shows
Mar 22 16:25:53 ip-10-139-23-91 (local7.notice) proxy[6877]: NOTICE: 
<script>: Authentication failed, invalid user - 
R=sip:420800123456 at sip.myvoipex.net 
ID=7cf1d52725c1a9983404ebd9630c1054 at 1.1.1.1.68:5060 UA='ipbx'

can you recommend best practice settings for pbx trunk?

system: mr4.2.1  AWS
