VOIP.MS - Grandstream HT802 - T-Mobile G5AR
Has anyone had any luck getting this combination to function correctly. I've tried pretty much every suggestion I've been able to find with Google. I even tried inserting it after a router running off of the G5AR, which is working perfectly with everything else on it.
The closest I've gotten so far is; when dialing out, there is a delay, then a busy signal, when calling in, the phone calling in has it ringing, but the VOIP phone stays quiet and dark.
I tried getting help from T-Mobile, but they tell me it's an issue on the VOIP ATA side.
Thoughts?
