    Thanks Miguel,

    However the twilio host which I have configured in the “Remote Host” field is a FQDN instead of IP address.

    As you rightly said the twilio FQDN vpbx-apptomato.pstn.ie1.twilio.com resolves to the following IPs :
    54.171.127.193
    54.171.127.194
    54.171.127.192

    Also I have configured the above IPs in the firewall  whitelist

     

    If I configure an IP address and when Vital PBX sends an outbound call it may add ip address as hostname instead of the fqdn and Twilio may reject the invite.

    Secondly can add multiple IP addresses in the host field or with prefix max?

     

    I am attaching an screen shot for your reference
