SIP Configuration Problems/Cause 20 Subscriber Absent

[atsatlantic57]

Hello all, I'm installing vici for the first time. I've hit a snag regarding the SIP settings. When I try to manually dial out, I get "Cause 20:Subscriber Absent"

Configuration details are as follows:
Version 9.0.2 200415-1712| Asterisk 13.29.2 | VPS Ubuntu 20.04 x64 | 4core 160gb 8192 ram| Was installed using most recent vicibox iso.

I was able to feel my way through it all the way to the point of adding a sip trunk. Should also note that the firewall on my vps is currently disabled.

Config:

Reg String: Blank. No Credential List Active. IP Control Lists the IP Vici is hosted on.

Account Entry:

I'm definitely out of my depth here, but if anyone can help me find a resolution to this or at least point me in the right direction, I would be eternally grateful! Thanks in advance.

are you sure your SIP trunk has active channels? Did you pay for channels?

[Kumba]

Call your carrier and see what they require you to use for SIP. Subscriber Absent sounds like they're expecting you to register to them as an authentication measure.
