Access Control List
FreeSBC will automatically create Access Control List for each NAP you created.
If you double-click one of the created ACL, you will see FreeSBC only accept the calls if source IP matches. In this sample; the calls from 192.168.1.10 will accepted only.
SIP DOMAIN
A SIP domain represents a grouping of devices (or users) that can communicate with one another. You must configure SIP Registration Domain for your system. The first step in doing so is to create a SIP Domain:
Create New SIP Registration Domain
1- Click SIP Domain in the navigation panel
2- Click Create New Domain
3- Create the new Domain:
- Enter a configuration Name for this domain.
- Enter a Domain Name for the SIP Registration Domain (the domain can be an FQDN or an IP address)
- Set the number Maximum Registered Users for this domain
- Set the Expires value used by SBC when the remote device doesn't supply one (Default Contact Expire)
- Select Routing Method the system will use to route calls to registered users (if enabled in routing scripts).
- Register source: Sends SIP Invite to the registering source IP address.
- Contact: Sends SIP Invite to the 'contact' from the Register message.
- Set the Default Contact Expiration, this value will be used when no Expires value is supplied by the user agent.
- Set the Minimum Contact Expiration, this is the minimum Expires value that can be supplied by a user agent. Lower values will be rejected with a 423 'Interval too brief' response.
- Set the Maximum Contact Expiration, this is the maximum Expires value that can be supplied by a user agent. The higher value is replaced by this parameter.
- Forwarding Parameters:
- Select the Registration Forwarding Mode to the registrar:
- Contact Remapping: Changes the user and the IP address.
- Contact Passthrough: Doesn't change anything. Enables devices to be contacted directly without going through the SBC.
- Set Minimum Registrar Expiration, this is the minimum Expires value sent by the SBC to the registrar. If a user agent 'Expires' value is greater than this parameter, the SBC will do rate adaptation between the user agent and the Registrar.
- Set Maximum Pending Register Forward, the maximum number of simultaneous pending register requests allowed for this domain. New REGISTER request is being refused passed this threshold.
- Set Maximum Simultaneous Register Forward, the maximum number of simultaneous active register requests allowed for this domain. New REGISTER request is being refused passed this threshold.
- Select the Registration Forwarding Mode to the registrar:
- Click Create
4- Verify that the Sip registration domain was successfully created message appears
5- If your registrar has multiple domains, you need to create all the domains one by one.
Create New SIP Registration Registrar
A SIP registrar represents a SIP endpoint that provides a location service. You must configure SIP Registrar for your system. The first step in doing so is to select your SIP Domain:
1- Click on your domain in the SIP Domain List
2- Click Create New SIP Registration Registrar
3- Create the new SIP Registration Registrar
- Enter a Name for the SIP Registration Registrar
- Select pre defined SIP Proxy NAP from drop-down menu
- Click Create
4- Verify that the Sip registration registrar was successfully created message appears
Associate a SIP Domain with the new NAP
Associate a SIP Domain with the new NAP. If you have more then 1 registrar domain using the same registrar you can associate all of them with the NAP:
- Select a sip domain from the Available list
- Click "<<" to associate the SIP Domain with the NAP
ROUTING
You must set up call routing for your system. Call routing refers to the ability to route calls based on criteria such as origin, destination, time of day, service provider rates, and more.
Route Configuration for Remote Workers to SIP Server

Activating the Configuration
Changes made to the configuration of the FreeSBC units are stored in the OAM&P Configuration and Logging database. In order for changes to be used by the system, they must first be activated. This is done at the system level and accessed from the Navigation panel.
Check the following link for activating the configuration;

- Domain/Realm - IP address/ FQDN configured in the SIP Domain. In our example it is mydomain.com
- User Name - Username configured in the SIP server for this user
- Authentication Name - Authentication name configured in the SIP server for this user. Usually, it is the same as the username.
- Password - Password configured in the SIP server for this user
- Yealink T27G Configuration
- Username - Username configured in the SIP server for this user
- Register Name - Authentication name configured in the SIP server for this user. Usually, it is the same as the username.
- Password - Password configured in the SIP server for this user
- Server Host -IP address/ FQDN configured in the SIP Domain. In our example it is mydomain.com
