Bria 5 SoftPhone & FreePBX 13 Asterisk -- Need help with Configuration

We are trying to setup softphones with Bria 5 desktop client. It is not making incoming or outbound calls, even though it is connected properly. We need this fixed quickly for a project. It should be a quick fix. Job is easy and can likely be done in under 15 mins. Once complete, provide us with appropriate configuration setup for client for future.
