Create/Modify a NAP with RestFul API

You can create/modify a NAP in your system with RestFul API using JSON format. The JSON must be in the following format:

Most important fields in the JSON file

• name = NAP name
• proxy_address = NAP Ip address or FQDN
• proxy_port = Port to communicate with the destination
• sip_transport_servers = transport server to use in ProSBC to communicate with the destination
• port_ranges = RTP port ranges used for this NAP
• authentication_parameters = If you want to authenticate this NAP to the far end you need to fill up the parameters under authentication
• registration_parameters = If you want to register this NAP to the far end you need to fill up the parameters under registration

Adding a new NAP

You can add a new NAP with the POST command:

POST http://ProSBCIP:12358/configurations/configuration name/naps/

ProSBC will create a new NAP from the name in the JSON file.

Example: We use the Postman tool in this example and the URL is:

http://192.168.1.25:12358/configurations/config_2/naps/

If the new NAP is created successfully, you will see the following information in the Postman Tool

Modifiying a NAP

You can modify the existing NAP with the PUT command:

PUT http://ProSBCIP:12358/configurations/Configurationname/naps/NapName

Example: We use the Postman tool in this example and the URL is

192.168.1.25:12358/configurations/config_2/naps/TEST_NAP and changed the proxy_address from 192.168.1.99 to 192.168.1.100

If the update is successful you will see the following information in the Postman Tool
