Grandstream....months later.

Yeah, I get it. I briefly had a 503 - fxs port for house line and fxo for the emergency (free) pots line from verizon (free because the triple play I signed up for is quite a bit less than the separate tv and internet i had before.) Anyway, I really liked the early dialing feature it had (so, for example, my asterisk dial plan could result in 411 or 7-digit dialing going more quickly without needing to wait N seconds.) Unfortunately, it was flaky, and at least once a month, the fxo port would just stop working - requiring a reboot. Given that the main thing I was using the fxo for was 911 (since even though I have voipo 911, the verizon one is more likely to work - not subject to the vagaries of the internet), this made it useless to me. It went to the junkpile.

New Firmware Version 1.0.1.42 in Beta. While .41 is more reliable and stable than any previous version, it wasn't quite there yet as far as registration issues (in my experience-but was very close). Time will tell if .42 catches 'em all.

Give them some more time. They'll get it right eventually...
OTOH, One should be grateful that GS still supports the HT502; other companies do not that anymore! they simply suggest their new product lines as "the fix", or simply move on to a new market
sorry about the rants
