Hi,
I have 3 home workers each with a site to site VPN connection. At each site is a PC and Grandstream phone (2000 or 2020). The VPN is running, the PC can connect through and I have confirmed that registration packets are hitting the 3CX server.
One out of the 3 phones is working. It registers successfully and makes calls without issue. The other 2 have the same issue, where it does not do the second pass registration. The packet trace is showing that it just cycles through the registration request and 3CX responds with 407 Proxy Authentication Required.:
I have checked (quadruple checked) the Grandstream settings and they are configured exactly the same except for the User ID and passwords obviously. i have also got the user to install the android client on his phone and connect from home and using the same account settings is able to connect successfully.
I am thinking this may be a natting issue, as the android has the Nat helper option.
Any help is much appreciated.
thanks
Mark
