To preface, I doubt this is the right subreddit for this, if anyone has any suggestions for where this post should go I will post there and take this down.
I recently got a Snom D717 desk phone at my office. I was given permission to take a VTech VH621 headset off a different phone we have since it wasn't being used. It was paired to a Snom A230 DECT dongle. I took the dongle and connected it to my new desk phone. However, the headset now just beeps once every 20 seconds or so and says "Out of Range", and nothing I try gets it to reset or deregister.
Things I've tried:
Deregistering the dongle, both in the old and new phone.
Removing the battery from the headset for a few seconds and reconnecting it.
Following the normal setup process and leaving it sit for around 5 minutes.
At this point, I don't see any way to reset the actual headset, despite resetting the dongle 5+ times. No matter what I try, all it does is say "Out of range."
Again, I apologize, as I know this is very likely the wrong sub for this, but I can't find any help or additional instructions from either Snom or Vtech, and I couldn't find a dedicated subreddit for either of those brands, so I posted this here. Our phone system is 3CX at least, if that makes a difference.
Thanks in advance!
EDIT: I called VTech, and their solution is below. This was not publicly available, I had to call them for them to provide this info. I think it's an annoying business practice to not publish simple support items like this and force people to sit through being on hold with phone support, so I figure I'll save some people some heartache and post these instructions:
In order to completely factory reset the headset and get it back into pairing mode, press and release rapidly the keys in the following order:
At this point, the headset should be in pairing mode with the Power button flashing red and blue slowly. Proceed to pair like normal.
Thank you for the update and the edit on the original post, this is something more to do with the Vtech product and while I understand your frustration for not finding these info online, I am glad it was solved by contacting Vtech directly.
Have a nice day
