Inbound Call drops after 30 seconds

[Rob Davies]

We have discovered an issue that is affecting a number of our customers using Polycom VVX. The issue is quite specific as described below:

Internal User answers a call on Polycom VVX 411 running firmware 5.8.1 from a remote user who is connected externally via SfB Edge.

The call lasts approx. 30 seconds then terminates. The trace shows the Polycom handset sent a Bye and hung up the call.

This problem appears to be linked to the latest SfB rollup being installed on all SfB servers.

• This problem does not exhibit itself if both users are internal.

• The problem is resolved by rolling back to Firmware 5.7.3

• Firmware 5.8.0 also exhibits same issue.

• The problem appears to only happen on an inbound call when Polycom is the answering device

Any advice on this issue would be welcomed.

Thanks
Rob Davies

Hello @Rob Davies,

For your new issue we have had isolated reports of this where customers brought this to our attention via our Support Organisation.

We have made changes to our code to accomodate this corner case but this would need to come into our support organisation to double check that the issue is the same.

We fixed this for our other customers and include this in the next 5.8.2 release which is currently planned for the 15/11/2018 (Subject to change) but without any logs escalated into our support organisation we are unable to verify if you are seeing the same issue.
