Solved 3cx > Nextiva Configuration Settings

[TechUpgrade]

Does anyone have experience with Nextiva as a SIP Trunk? I have been working with Nextiva and they are all but worthless when it comes to troubleshooting anything 3rd party like 3CX. I have been able to register my trunk with Nextiva and I can receive inbound calls. When I attempt to place outbound calls, I receive:

Call or Registration to 812XXXXXXXX@(Ln.10001@TRunk) has failed. XXX.173.144.74 replied: 604 Does not exist anywhere; from IP:XXX.173.144.74:5060

On the phone, I dial and it immediately closes connection.

Any help from anyone would be greatly appreciated! Im about ready to pull my hair out with Nextiva even though they are "3CX Compatible".

So I changed the following settings on the SIP trunk Outbound and resolved the issue:

I changed ALL Remote Party ID" settings to "Leave Default Value", and outbound calls are working properly now.
