REST API access in SBC

Hello,

we have SBC 6100 with firmware: Acme Packet 6100 SCZ8.3.0 MR-1 Patch 11 (WS Build 526). We are not able to access the 6100 SBC rest API.

 

We tried :

rest/api/supportedversions

auth/token

many versions

 

We always receive 404 not found.

We have configured:

web-server-config

    state                  enabled

    inactivity-timeout           20

    http-state               enabled

    http-port                80

    https-state               disabled

    https-port               443

    http-interface-list           GUI,REST

Is there anything else we need to configura in order to get REST API on this SBC
