HT-502 more reliable now?

**voipinit** · 05-02-2009 08:31 AM

Just wondering, the very few issues I had with the Grandstream disappeared entirely once I was moved out of the Planet (some weeks ago). I would be curious if Grandstreams problems of the past are gone. Yes, I do understand 'if it ain't broke - don't fix it' which is the situation with the PAP2Ts, but just wondering.

Seems to me the Grandstream's major flaw is its inability to reconnect after a disruption.

If then there is never a disruption then one would never have a problem this way.

Im betting with the change of datacenters the intermittent network disruptions have disappeared so the Granstream's will stay connected better...

Good point! Maybe that's why I never had a problem with my HT-502 when I was a VT subscriber, their network never went down, seems kind of unlikely though. I'm betting it did go down, but I never noticed since the GS re-acquired, which may now might happen with the VOIPo network as well. I know it's not from a different GS ATA since I am using the same one.

I have an asterisk box that I connect my HT-502 to on a LAN, so there is not likely to be any connectivity or latency problems. Yesterday I found the 502 to all of a sudden NOT be registered to my * box anymore. I rebooted it and it re-registered and started working again. Sounds very similar to the problems VOIPo was having with them. It was connected for a couple of days and then suddenly disappeared. It is running the .21 firmware so I am thinking about backing it down to an older version.

if the HT-502 is yours, you can try you luck

at using the latest beta firmware

I replaced my 286 with a 503, only because in addition to my voipo line, I have a (basically) free POTS line from verizon, so I use that with my asterisk server and toll-free/911/411 calls go out the pots line by preference. I have not noticed any issues with registration failures. I'll read the release notes for the beta firmware though.

Yep, exactly.

Interesting. Lots of bug fixes that's for sure. I've never been a big fan of Grandstream's stuff, but I have had good experiences with their support. I had an old Handy Tone desk phone thing that was messed up out of the box, and they helped me a lot with new firmware and such to get it working.

Where was Grandstream when we needed them?

I thought I'd post a follow up. I haven't had any trouble with it since I posted last. I think part of my problem was related to the time sync. I noticed the time on my Asterisk box was WAY off and drifting badly. I am running * on a virtual machine and have since fixed the time problem. I wonder if maybe the registration time was so screwed up the 502 was confused? The 502 also syncs its time and was correct, but the * box was totally goofed up.
