v18 and v20 failed canceled on RG Ring all

[ElementalWindX]

I have a pbx with yealink desk phones and yealink cordless phones. Randomly my client is getting a 'failed canceled' on their RG Initial Ring All (84) ring group. There is a single dect going to 2 cordless phones in this ring group as well as 6 other yealink desk phones.

Any idea what could be causing this? It's random as most calls will go through.

Thanks.

Maybe one of the phones are in DND mode?

They're all green in the team view.

Check and ensure that the firmware on the DECT and handsets is the same as mentioned here and also for the regular desk phones is the same as here.

We upgraded the dect and the handsets. This seems to have solved it. We've gone 24 hours without a failed/canceled. However the handset randomly will display a "Synchronizing..." or "Out of range" message. The dect base is right beside the phone when they are trying to call out and getting these messages.

They have two different model handsets working on this dect. One is fine (W53H, oldest one). The other is not (W56H)

Should you get in touch with the vendor team to see if they can advise there and maybe guide you in the right direction and settings of the DECT/Handset?
