Flowroute Registration Errors

[biggreyphone]

I am using hosted version of V20 3CX with Flowroute as my trunk and have been receiving dozens of failure to call or register on outbound calls daily with the following message below:

Call or Registration to XXXXXXXXXXXX@(Ln.10000@Flowroute) has failed. sip:34.210.91.114:5060;lr replied: Forbidden (403)

I am able to make and receive phone calls without issue. I am using account based registration from with Flowroute in 3CX. I contacted Flowroute and they see NO issues on their end and suggest that it is a 3CX issue and that they evaluate this. I can't do any packet captures yet because it is not yet available in the hosted 3CX instance.

Ideas?

Ok. This looks like a 3CX issue, not a flowroute issue. I deleted the Flowroute trunk and re-added it and the same error messages are coming up very soon thereafter. I added a second trunk through Telnyx with IP authentication and now I am also getting the same error registration message [403] with the Telnyx trunk. On the Telnyx website, it shows the trunk is registered fine. I dont really want to use a ticket since calls are working correctly

Have you also confirmed that the ip is whitelisted from the provider?

We can check and advice further on this but we will need to proceed with a support ticket.
