Configuring IP Phone over SBC

[blossoms]

I am a novice in Linux and am setting up my first Cloud hosting on AWS Lightsail. I have installed the PBX on my instance and I can see a static public and Private IP addresses. Whilst the FQDN is mapped to the public IP, the Private IP (172.x.x.x)is redundant. All port forwarding had been done by PBXExpress at installation.

I trying to reconfigure an existing Raspberry Pi3B 32GB as SBC. Using https://www.3cx.com/docs/installing-pbx-raspberry-pi/ I got stuck at 3.2: "...login with the default user..." using what? I have tried OpenSSH on Windows but could not get into the Pi interface.

Somehow, I observe that SBC is Up on my Console's SIP Trunk and correctly identified my network's WAN IP as its Public IP but got IP address from my local network (192.168.x.x) as its Local IP.

The issue I'm having now is that I am unable to provision IP Phones. Should I be changing my local network to the Class B 172.x.x.x range to match the Cloud private IP which may cause a different issue?

I'll appreciate anyone's help.

PI login issue

1. To log into the PI, you need to have a screen , keyboard connected directly to the device
2. To access the PI remotely, you need to enable SSH first https://www.raspberrypi.org/documentation/remote-access/ssh/

Note : The PI should only be running 3cx sbc software

Your local phone IP range can be any RFC 1918 address - 192.168.x.x address range is fine - does not have to match your cloud private IP

What issues are you having in provisioning the phones - what type of phone ?

Thanks Saqqara, that link is very helpful. Provisioning the phone shouldn't be a problem as I have done many on-premises in the past. This time am provisioning Yealink T42S with latest firmware. Like you rightly pointed out, the issue is login to Pi.

Originally it had 16GB SD and was configured as SBC for a different site where it is no longer needed. So, I inserted a new 32GB SD to install SBC. I am now getting "access denied" because I don't know the password used to set it up previously. Any idea how to wipe this and start afresh?

To avoid further headaches, I abandoned the Pi 3B for a new Pi 4B which is working well now. Thanks.
