Hello All, I have one Freeswitch 1.6 server installed on CentOS 7.2 64-Bit. I configured one gateway to make outbound calls and one extension. Registered that extension on softphone dialed a number. Its working. Extension => Freeswitch => Gateway => Mobile =======Working After that registered same extension on an Asterisk server and from Asterisk dialed a number and then also working. Asterisk(with username/password) => Freeswitch => Gateway => Mobile ========Working. Now I am trying to remove registration from Asterisk and send directly call to Freeswtich and on Freeswitch check if that IP is allowed then allow IP to make call. I added Asterisk IP in Domain ACL on Freeswitch but when call called from Asterisk, its going in Public context and considered as a incoming calls. How I can add IP based authentication for end user and route call to configured gateway? -- Thanks & Regard Uday. Mobile:- +91-9377579349
