Spent all weekend trying to get this to work with Snom,Aastra & Grandstream deskphones with no luck but can connect the Android client.
Can anybody tell me if the external extensions must be connected through the SBC rather than a direct connection?
Wireshark shows the phones trying connect but the system replies with a 407 Proxy Authentication Required then nothing else.
It's not the firewall as I've installed 3CX directly onto the OS and I can connect an external extension to that.
I'm running this in a datacentre on ESXi 5.5 on MS Server 2008 R2 64bit behind a pfSense firewall. (If I can't get this to work I'm going to have to revert to one 3CX per OS.)
Many thanks
Gary
