Sip Username

This is used for provisioning purposes.

Authentication Mode

There are 2 types of SIP:

Account

Username, Password, Server Domain are required to register a SIP account

IP

Fill in the Transport Protocol, IP Peer, and Port to register the SIP account.

Transport Protocol: choose the protocol you would like us to send to you,
- UDP
- TCP
- TLS
IP Peer: fill in your IP Address. We will only send the voice to and charge the usage of this IP address.
Port number: Ports are standardized across all network-connected devices, with each port assigned a number. Most ports are reserved for certain protocols — for example, all Hypertext Transfer Protocol (HTTP) messages go to port 80. While IP addresses enable messages to go to and from specific devices, port numbers allow targeting of specific services or applications within those devices.

SIP Password

This password will be used for provisioning purposes if the Authentication Mode = Account.

There are two ways to reset and get the SIP password:

Automatically generate a password
Create a password

Password policy:

Length = 14
Requires at least one uppercase letter
Requires at least one lowercase letter
Requires at least one number
No reusing of last ten passwords

SIP Server

We provide 2 types of information here:

Sip Domain: Use sip<x>.b3networks.com (e.g: sip5.b3networks.com) if the Authentication Mode = Account
