Polycom Trio loses SIP connection when Visual+ plugged in

[gnyce]

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.

UC Software Version 5.7.2.3205

- doesn't matter if the Logitech camera is plugged in or not.

- the logs seem more indicative of trying to upload some core-dumps on the Visual+

- going to try to un-pair the devices, reboot both... wait a bit.... then re-pair

(theory being that the pairing was done after the Trio was on updated firmware, but the Visual+ was not)

[gnyce]

immediately after re-pairing, same issue occurs.  Found all sorts of logging, but can't make sense of what I'm seeing yet.

Next approach - pair again and then downgrade to a previous firmware (if that is allowed).  

[gnyce]

Downgraded two versions  -  5.7.2.3205 --> 5.7.2.3123  -->    5.7.1.4145 (currently)

No apparent change whatsoever.   So maybe this isn't a either a 1) new software bug or 2) it's more a configuration issue.  Find it hard to believe no one has hit this previously.  

[gnyce]

Saw an old ticket about issues experienced where there was no provisioning server.  Fair enough, set up an internal FTP.  Did not seem to help (though I can get logs this way).  Frustrating - this is the (as far as I know) last piece inhibiting me from deploying this... the SfB integration is pretty neat, but I still need to support a SIP line2. 

[gnyce]

Not so sure about this being a 'configuration' issue now.  I've tried all sorts of tweaks and combinations, to no avail.  Tried 3 different S/W versions, no change.  

Trio P/N: 3111-65290-001 RevA

Visual+: 2201-66420-001

Going to run the phone w/out the Visual+ for a bit, make sure all works (SfB, SIP/Line2) for the long-haul.  

I'm at a loss.  Open to ideas, even if it is logging (e.g. what to look for)

Hello @gnyce,

welcome to the Polycom Community.

Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.

So in trying to find the ticket/entry where I set up the 2-line/hybrid setup (and the "TrioMultipleLines.cfg"), I found this:

https://community.polycom.com/t5/Skype-for-Business/Trio-8800-hybrid-registration-default-call-mode/...

so my answer seems to be that I need to tweak the video.callMode.default....  some minor success so far.  Encouraging!
