Good afternoon everyone,
I have a simple question and am hoping some others have also had this issue and been able to resolve it.
Basically I use a UCM6301 behind a Draytek 2865. Evrything has been working perfectly for about 6 months now with no noticeable issues.
Today I activated VPN connection on the Draytek router using a PPTP connection to PureVPN so as to make the link more secure. Everything is still working fine within my premises and also on the UCM6301 apart from remote connect. The Wave app on my mobile devices still connect to GDMS okay but when trying to make a call they just go to air. This includes calls inward and outward to the devices. The UCM6301 also reports that the extensions are still connected.
With the VPN turned off and the remote connect troubleshooting is run, this is the result.
With the VPN switched on, this is the result of the troubleshooting
I am fairly sure I am just overlooking something very simple, but have been trying various solutions over the past few hours to no avail. I do have STUN set within the UCM6301 and just cannot work out why this is the only issue I am getting on my whole network.
If you require any further information, then let me know and I will collate it for you.
Any help or pointers would be greatly appreciated.
Many thanks in advance
