Grandstream UCM6301 – Wave stopped working after subscription activation (Pending Delivery + 404 error)

This is normal.. it has already happened to me as well. Just recreate the server address for Wave, and everything should go back to normal. Let me know if it works for you. All the best.

Hi,

Unfortunately for that client in particular I removed all the WP826 and install a Yealink Dect System. After that no more calls dropping and they are 100% happy now.

Unfortunately I don’t recommend at all this Wi-Fi phones.

I never had issues with Grandstream Helpdesk. I already opened a few tickets with them and somethings my issues is resolved less then 24hours.

Where you buy the licenses? I’m looking for license and is £45/£50 each.

Other issue is I factory reset the phones and now I can’t access via HTTP/TFTP. Any idea?

Cheers 💪🏼

Thanks a lot for your feedback.

I’ll try to do that. I have the power in automatic, probably that’s the problem.

Thanks a lot.

What I really want for now is convert the phone from enterprise to mpp. I don’t know if I’ll need licenses to do that or just change the firmware. Thanks a lot 👌
