This is an odd one. I have a Trio 8800 and a Visual+, and a Logitech C930e plugged into the Visual+. All firmware updated. I have connectivity between the two devices. The Trio is logged in to SfB, and in addition it has Line2 configured for a SIP extension. Both skype and SIP/voice calls work.
However, here is where it gets weird. When I power the Visual+ on (POE from the Lan-Out on the Trio), the Trio will no longer be able to make outgoing SIP calls. It can still receive incoming... but outgoing is broken (fast-busy). If I unplug the Visual+ and restart the phone, it works again - and will continue to work, for hours... up until I plug the Visual+ back in.
- Trio and Visual+ on on the same subnet, no firewall in between them.
- outgoing-call breakage happens as soon as the Trio shows a blue 'link' icon (top-right)
- also doesn't matter if the Visual+ is connected to the Lan-Out on the Trio, or a different network jack.
Attached is what gets logged on the Trio... not sure this is meaningful.
