we have about 75 Grandstream GXP2000 phones running with Asterisk 1.2. 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 _______________________________________________ Sign up now for AstriCon 2007!
