Dumb Question about 3cx Windows Softphone

[Sean Foley]

New to 3cx, yadda...

Anyway, basically no matter what I put into the client the software always goes to my external address rather than using the LAN. What's the magic to make this do the thing I want it to do? The client is running with TLS, Secure RTP, tunnel on. What I'd like it to do is: Go LAN 1st, go WAN second even though in this case the computer would never be "WAN" because it would VPN into the network that the PBX resides on. Any ideas? Right now, it goes only to external FQDN even though it is provisioned to the internal address.

Reboot didn't change anything... But, yeah... I didn't.

When you go to extensions/provisioning you set the clients to the lan?

what I did... was set the client to specifically register via the LAN IP.

It does this... It doesn't communicate directly however....

What it does is:

1) Seems to go to my FQDN

2) Router/Firewall figures out it is port forwarding for that port and answers for that address. Re-routes it toward the PBX box. If you go to the pbx and netstat...

3) Connection seems to be coming from "external address" to whatever ports it wants. In this case 5161, 5090, etc.

4) All connections look like they're coming from that router even if they are on the LAN.

If you disable the port forwards the client stops working entirely even though you'd think naturally they'd work.

You resent invite email and reprovisioned?

You resent invite email and reprovisioned?

Deleted the extension and reconfigured it several times, and also blew the "mac" out of the phones section afterwards. Recreated it and still having same issues... I'm not configuring the client by hand either but using the file supplied in the welcome e-mail. I've manually deleted the account configuration out of the 3cx client as well.

It sounds as if you don't have internal FQDN supported.

Under phone provisioning for the 3CX client what is in 'Network interface for registration and provisioning' - does it have a fqdn or ip address of your 3cx server

You could try changing it to ip address and resending the welcome emails

If fqdn , as leejor as suggested you need to setup internal dns to point to 3cx server
