Registration types

Registration without IP with password
If you do not have a static public IP  provided by your Internet provider, select this option. Use it for SIP phones and clients, including mobile ones for Android, iOS or for your PBX. Name and password will be created automatically. After creating a registration, all the information about the phone / account will be displayed. If you want to change your settings - click the "Update" in the menu > Settings. In the "Registration", you will find your account name - here, the account name and login name are the same. The allowed codecs are aLaw, uLaw, and G729 - SIP EXPIRY is 300 seconds. SIP port 5060 and RTP port range is between 10000-20000.

Registration with IP and password or without password
If you have a static IP address and a PBX, then choose this type of registration. It's safer if you combine it with a password. For the devices which do not support password authentication, select "without-password", but pay careful attention to the correct settings of your firewall. Enter your IP address, and click on the "Create" button to finish your registration. After creating a registration, click on "Update" to go to other settings. In the "registration", you can find your account name - the account name and login name are the same. The allowed codecs are aLaw, uLaw, and G729.
