DECT phone system sending busy/unavailable.

[North40IT]

I am having an issue that only started occurring with Version 20 upgrade, (we are self-hosted on premise). If we have a yealink IP phone and a yealink DECT phone tied to the same extension (Retail environment, employees not tied to a desk, need to move around with a phone) When we call this particular extension or the ring group to which the extension belongs the DECT system is responding with an unavailable/busy which would be ok except that the IP phone of the same extension doesn't continue to ring. It seems as if there was a behavior change in the upgrade with how the PBX handles the status of DECT SIP responses vs IP phone SIP responses. The portable phone was not in use, it may be turned off or lost, i'm having them track it down, but if that's the case, the desk phone is still available and should continue to ring?

Have you tried taking the DECT handset offline and calling the extension to check the deskphone rings? Then do the same test the other way. Once you establish the DECT is causing the issue I would then a) check FW b) factory reset it and perform tests again.
