3CX to FlowRoute Outbound Call Failure

[Whitey436]

I am running a new 3CX V12.5 server install with FlowRoute. It has never worked as of yet. I have Cisco 7960s and a couple Android extensions. The Firewall Checker runs successfully but I cannot make any outbound calls. Any help would be appreciated.

Here are the log entries.

The 3CX set-up instructions from Flowroute seem pretty straight forward..

https://support.flowroute.com/customer/portal/articles/1849185-3cx-phone-system---add-flowroute-as-voip-provider

But your logs would seem to indicate that the authentication method that you are using, is not working (they don't like it).

Cause: 403 IP Based Authentication Required

You may want to contact them for more information about this.

Did they ask you to provide them with a static IP that your calls will originate from?

Yes, I did add my external static IP to the authenticated outbound call list on the FlowRoute site.
Thanks for pointing me in the right direction. I felt like the 3CX setup process was pretty easy as you said.
I will contact FlowRoute and post my results.

Thanks!

I contacted FlowRoute and they were able to help solve the issue.
Admittedly, it was a 3CX config issue not something on the FlowRoute side.

While the 3CX config for FlowRoute is straight forward, there really needs to be two options:
SIP Authentication or IP Based Authentication.

I was intending on using IP-Based and had configured FlowRoute as such. The message back from FR when attempting the call confirmed that they needed IP-Based configuration to be delivered to them in order to complete the call.

**
In order to support IP-based authentication on the 3CX to FlowRoute, which is NOT included in the current config notes, is that you must modify the Outbound Rules to PREPEND your FlowRoute 'Tech Prefix' plus an '*' to any outbound call.
**
As soon as I added this to my rules, my calls worked perfectly.

Thanks for your help on this matter.

Thanks for posting this tip - I was wondering how to do IP Auth with Flowroute.
