Hi, Has somebody experiences with the Grandstream GXP2020 / 2000 phones in a business graded installation (with really traffic on .... not 3 calls a day ;-) ) Of course with Asterisk PBX (1.4.1 or 1.4.11 or 1.4 in generall) Thanks! Kind Regards, Erik

The only complaint I had from a very busy installation (a travel agency) is that the handset gets hot after prolonged use. This may have been because the office itself was hot during summer and after they installed an AC the problem is no longer there. -- Telecomunicaciones Abiertas de M?xico S.A. de C.V.

> Has somebody experiences with the Grandstream GXP2020 / 2000 phones in a > business graded installationI'm afraid I can't give you as positive feedback as you've had from other posters. I did quite a few installations with GXP2000s about 18 months ago, and they've caused us nothing but problems. Firmware started off as truly abysmal - half the features that the phones were sold as "supporting" didn't exist, and it wasn't until the more recent firmware that they were added. In the early firmware the speakerphone was practically unusable. In later versions they sorted out the echo problem by making it quieter, so it was still unusable in anything apart from a quiet single office. There was also an issue where 2 versions of the hardware were out there and a firmware update managed to kill the LCD display on a whole raft of phones. We upgraded the 3 offices left that hadn't replaced them with something else in one go. 2 of them worked fine, I had calls the following day from the third office saying none of their phones had any display. They've mostly fixed it in very recent releases, but I still have the odd one or two phones out there where the display just vanishes from time to time for no reason. Ignoring the firmware trials and tribulations for a moment, one fact still remains: the handset feels cheap and tacky, and compared to the Linksys SPA942 call quality is noticeably inferior (even LAN-LAN using g711). Here in the UK, the SPA942 is only about 10GBP more than the GXP2000 which makes it a much better choice. 2 of the 3 offices which had GXP2000s have replaced them with SPA942s over the last 6 months. The final one will be replacing the GXPs in a few weeks when they move office. It'll be like a support weight lifted off my back when we finally get rid of them all. [if anyone in the UK wants some second-hand GXP2000s I have quite a few, about 18 months old, in good condition :-) ] Regards, Chris -- C.M. Bagnall, Director, Minotaur I.T.

We also have about 25 Aastra 480i phones in our call centre and 10 Cisco phones in meeting rooms. The Grandstreams work fine on the whole, they are probably good value for money in smaller installations. We use some simple bash scripts to manage the configurations so the need to convert the config files from text to a binary format is not an issue. Sound quality is OK, the speaker phone is not great. Most users are happy with the Grandstreams but we give Aastras to anyone who spends a lot of time on the phone. The reason I cannot recommend these devices for larger installations is the mediocre response from Grandstream's technical support. Tech support will acknowledge your initial problem report but then ignore you if they don't have an immediate fix. This is a pattern repeated over several reported incidents. Our latest issue is with the GXP2000's running f/w <= 1.1.1.14. The phone does not send a "keep-alive" packet when the mute function is used, despite this bug being documented as fixed in a much earlier release. This results in a disconnect after 5 minutes of being on "mute". Very annoying when on a conference call or on hold to tech support. This is fixed in 1.1.4.18 but this release introduces an issue with very loud (for our environment) ring tones rendering the GXP2000 unusable in our office. We no longer purchase Grandstream phones but will consider them again in the future should the support issues be resolved. regards, Drew -- Drew Gibson Systems Administrator OANDA Corporation www.oanda.com
We've a site with about 200 Grandstream GXP2000 phones, and they work quite well. We made some CGI Perl scripts to mass-deploy and manage their configurations from a MySQL DB into a TFTP server, where the phones go to download their binaries. With some initial work, now it has become easy to manage the site. All phones have firmware version 1.1.1.14; we are testing new stable version 1.1.4.18 but by now we found that some phones freeze sometimes - version 1.1.1.14 seems more stable. One thing they lack is the ability to dial alphanumeric contacts (URI dials), we hope future firmware corrects this issue. Older ones hadn't so much good hands-free speaker, but recent ones have a better DSP from Texas Instruments. Althow they're not the best choice in the market (like Cisco or Polycom), they represent a good price/quality ratio.
