I have the same issue with my HT802. I’ve been trying for days and can’t get it to work.
Have you tried creating a Sub Account and configuring your HT802 with that? This has been a solution for several of us.
I think the HT702 devices are going to be hit/miss. I got mine to respond and got into the settings this AM. Carefully entered the details per the wiki, saved stuff and rebooted.
And it never showed up again. Could see it on my router, BUT, refuses to provide VOIP and I cannot get back to the setting page. Just refuses.
I installed a HT802 for $55 from Amazon and things went better.
My HT702 for YEARS would require the occasional unplug to reset with VIOPO as well, after service went down and we got no calls for a day or so. I think its old hardware that is beyond its years. Last firmware was released in 2018. To recycling……
Berto you are awesome, thanks for this info it works now.
It must have something to do with the pw because my main pw (which i was told to use) does not even comply with the sub account setup requirements but whatever for now. Will try TLS tomorrow but for now thanks again. Now to go try to get my money back from VOIPo via paypal
I noticed the password issue too. It seems the main password lets you use certain characters that are not allowed in the sub-accounts. I thought maybe that was the issue with the main account not being able to register devices, but I changed the password and it still didn’t work.
Interesting, your comment about needing to reset the HT702. I had the same issue, but assumed it was my network. These devices are fairly inexpensive, so it may just be worth it to get a new one. Thanks!
