Battle with a Grandstream BT200 VOIP Phone

Thursday, January 28th, 2010

Much hassle trying to upgrade my fairly ancient voip phone which I use in the study connected to the Asterisk PBX.  It seemed to have a very early firmware and boot loader version, which no matter how much I tried would not upgrade to Grandstream’s latest and greatest.  I troubled their support ticket system for advice, and the persistent reply was that it would work in one go without intermediate versions.  Not so.  FAIL to Grandstream, I’m afraid.

After much searching I found a site called and there were a series of earlier firmwares.  I downloaded all I could, then set about seeing what could be done with these;  the phone was set to use a local HTTP server for the firmware upgrades, and by this means I could follow the Apache log and see the evidence of the files being sucked up.

From the very early software versions (on my phone it was software / bootloader) you do seem to have to upgrade in stages.  From GrandstreamSucks  I used firmware which upgraded just fine.  I then chose which also upgraded fine. THEN I used the from the real Grandstream site, and that seems to have worked fine as well.

Now all that’s left is to test it all out properly and check the configuration is still right.

Random Thoughts on Tuesday

Tuesday, January 26th, 2010

Very random.

Climate change:  the IPCC seems to have shot itself in the foot having predicted a few years ago that all the Himalayan glaciers would be melted in less than thirty years from now.  I really don’t understand how they can have come to such a dramatic conclusion without realising thy must have been so amazingly wrong unless they were simply joining the global warming bandwagon and giving politicians what they wanted to hear in exchange for funds.  It’s bad enough that the Pro GW enthusiasts can’t accept that they might be wrong.  Drives me mad – and somewhat irritated by some journals fanning the flames, it seems to me.  Gah!

— UPDATE, 27/01/2010: The Times has an article on this very subject and which strikes me as a far more balanced attitude to how scientists should think about this subject.—

The office canteen produced Haggis yesterday.  It was great.

Spent much of today looking at the conversion of to an MT based site.  Hopefully I can sort out the problems this poses me, and discover just hpw many pages there actually are.  Wget is now being run to try and get an  “independent” idea of what’s there.  Editor says 3500 pages, Script from SixApart finds just 980.  Nice bit of feedback from the publisher, though.

We went to Grace’s school this evening to hear about the proposed trip to Little Canada (IOW) when she gets into year six.  Got to find some cash, now!

Waitig for Grandstream to reply to my question about upgrading the BT200 phone firmware.  24 hours so far and no reply yet.  Hopefully they’ll comeup with the goods, because random crash and reboot only with a power cycle is a bit frustrating.

Time for bed.  Early shift for me tomorrow.
