Hello,

We've recently discovered an issue with call pickup above FW release 10.1.137.15.

Problem is, the phone which picks up the call (D385 on 10.1.159.12 f.e.) doesn't show the caller name anymore, only the number is displayed. The only fix I've found so far is to downgrade it to 10.1.137.15. All other versions newer than 10.1.137.xx cause the same problem.

Also I didn't find any usefull information in the release notes on at least something in this direction.

To me it looks like the D385 with the .159.xx firmware is ignoring/not using the identity display information in the NOTIFY message versus the D345 on .137.xx, which is using it properly.


Please help us with this problem, because we need to update around 7000 D-series phones which is on hold now because of this issue. If you need any further information, dont hesitate to contact me.


Thanks, Alex


That's how the pickup looks in the phones SIP logs. Please ignore the IP addresses - they're replaced by fantasy digits. slightly smiling face
