Ok, this has become my last resort for help...

Our provider has setup an Aspire system here at the main office for 30 phone inhouse, and we also have 5 IP phones and one softphone.

The IP phones and softphones all work ok internally over the LAN.

However, outside the main office, nothing connects.

I've checkd firewall settings on our PFsense firewalls (local and remote) and our VPN IPsec, PPTP, and OpenVPN. Everything works ok, we can access the network, access files and folders, ping any servers. EVEN ping the NTCPU of the aspire!

But for some reason neither the IP phones or the softphone can connect.

Via process of elimination, I'm pretty sure it's the aspire thats the issue. Is there ANY ports or settings on the aspire that need to be configured for this to work?

I've asked our provider but they are clueless, they keep hinting to buy their router to make it work. And I've yet to find a user manual on the NTCPU, does one even exist? I've also emailed NEC directly but they responded to contact my provider. Can anyone help!?!

I've read though thse posts on the forum:

But still no solution....

If I can't resolve these issues, we may have to return these phones.

Please, please, someone have answers...?

Thanks!
