This is a very important step !
The key information to connect with the SIP provider
Here, I use the example credential as;
SIP provider company name: Fast IPTSP
SIP provider IP-Phone number: +880.9678901234
SIP provider host: 23.220.75.232
SIP user: 9678901234
SIP password: mGc5hQd4ep
Extension number: 210
Extension password: hsu63b8vw9k2ntc
Elastix private IP: 192.168.48.10
Elastix public IP (MikroTik real IP): 52.85.12.118
Please replace your own IP and other credential
1) Configure SIP Trunk
Elastix GUI (remote access): https://52.85.12.118:54443
