UCS 5.8.0 drops intra-tenant, firewall-crossing calls when using Skype for Business Online

We use VVX 500 phones in the office, with a mix of UCS 5.7.2.1765 and 5.8.0.12848, all connected to Skype for Business online. There is no on-premises SfB infrastructure. 

 

We have determined that when colleagues outside the office call in using their laptops (with or without a USB softphone) to a colleague using a VVX phone with UCS 5.8.0.12848, the call drops after 25 seconds. 

 

There are no issues when:

  • The internal user initiates the call to the external user
  • The external user calls anyone outside the company/Office 365 tenant
  • The internal call recipient has UCS 5.7.2.1765 installed on their VVX phone
  • Internal users call each other, regardless of installed UCS version

Our office network is behind a SOPHOS UTM running the current build (9.510-5). All necessary ports are open and exempted from SSL inspection. 

 

Microsoft has not yet provisioned UCS 5.8.0.x to VVX phones connected to SfB Online. I assumed that was because UCS 5.8.x requires an update to BToE 3.8, so I turned off Microsoft's software provisioning and began manually updating phones to 5.8.0.x in a pilot program with parallel upgrades to BToE.

Re: UCS 5.8.0 drops intra-tenant, firewall-crossing calls when using Skype for Business Online

I'm pleased to report that after updating my test VVX 500 phones to firmware 5.8.2.4732, calls are no longer dropping after 25 seconds. 

 

I think the release notes mention this here, under resolved issues:

EN-107656 EN-109370 EN-109967 UC Software 5.8.0 VVX phones failed to accept the finalized peer-eflexive ICE candidates published by the far end.

Hello @JoeNaxion,

welcome to the Polycom Community.

The community's Skype for Business FAQ contains this post here:

 

Jan 17, 2017 Question:How can I troubleshoot simple Skype for Business, LYNC or Office365 issues?

Resolution: Have a look => here <=


You can try and use the above to get an idea of what is causing the issue and maybe post some logs for the community to look at.

 

Please be aware that Polycom employees cannot provide free support via the community and you would need to raise a ticket.

In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.

End Customers are unable to open a ticket directly with Polycom support.

If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you. This may not be who you purchased the Polycom device from.

If the unit is no longer within warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Re: UCS 5.8.0 drops intra-tenant, firewall-crossing calls when using Skype for Business Online

Update: the new UCS 5.8.1 release does not address this issue. Incoming calls still drop at 25 seconds.

 

@SteffenBaierUK, I know you're frustrated that we're not opening tickets, but consider this: My VVX phones are over a year old and out of support. That means I can pay $150 for the privilege of telling Polycom about the bug in their software, or post here as a warning to other SfB Online users not to upgrade their firmware just yet. 

 

I know Polycom does not monitor this forum to find bugs. I hope someone with an active support contract will tell them so we can take advantage of the 5.8 series firmware.
