I have a really baffling problem. A couple of months ago I purchased a pair of GrandStream GSX-2000 phones for use with Asterisk. At first all was well. But recently I've noticed terrible sound quality problems. Basically the sound will "glitch" or stutter randomly from time to time. Now, what is interesting is that this happens even with the phone totally disconnected from any network. You can hear it on the dial-tone that the phone itself generates if you press SPEAKER or lift the handset, with no network cable plugged in. So whatever is causing this glitching would seem to be being generated within the phone itself, and not coming from an external source. (It isn't the power, as the two phones are in different buildings in different towns. Besides, both are connected to UPSs). To me this seems to indicate a fault with the phones themselves. But for both of them to develop the same fault at the same time seems odd. I asked on the voipuser.org forum if anybody else had had similar problems, but everybody who responded said all was well with their phones. But given the wider reach of this list, I thought I'd ask here as well. Both phones have the latest firmware from the GS website. Does anyone have any ideas? Has anyone had anything similar happen to them? Faris. p.s. This is my first post here. Please be gentle with me :-)

[Asterisk-Users] re: GrandStream GSX-2000 strangeness
The Grandstream speakerphone is just about useless to me. I have a problem with their VOX not working right and if you try to mute a conference, the phone hangs up in a random period of time. I contacted their tech support and got this message from them: Dear Joe McConnaughey, Thank you for your email. Yes, we are aware these two bugs and engineering is working on that. The mute one is easy to fix but the echo (AEC) is not so easy to fix, but we are working on that and you should be able to get the fix soon. Thanks.

I have exactly the same problem with my GSX-2000. And am running the latest firmware. Although they seem like really cool phones in theary, practically I think they still have a far way to go. I personally can't believe they actually launched the 2000's with all the problems they actually have. Many of the advertised features on the GS website have still never been implemented in the actual phones themselves. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Faris Raouf Sent: 10 August 2005 18:28 To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] GrandStream GSX-2000 strangeness I have a really baffling problem.

Thanks to all who replied on this. But amazingly I think I've solved the problem. Basically I did a factory reset (select reset via the Menu key then enter the MAC address [as shown on the white label under the phone], then press Menu key again) and re-entered the necessary config details on both phones. And this has solved the problem completely (so far). Can you possibly give it a go to see if it solves your problem too Mark? What I don't (yet) know is the cause. It could be that the last firmware update somehow corrupted some of the existing settings, or it could be that prolonged use causes the problem, requiring a factory reset. I can still duplicate the sound problems in a way though. If you login to the phone's web config page, while listening to the phone giving a dial-tone, I can hear the same type of glitches happening every time I click on any links. So it seems that the source of the glitches is probably the phone doing something internal and getting stuck in a loop. GrandStream support also replied to my email on this subject, suggesting the possibility that it may be a hardware problem and asking for me to send them a copy of the phone's config.

I did a factory reset a while ago, but it didn't make any difference. This is my second 2000 since the previous one was sent back to the supplier for intermittent hanging or freezing up during use. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Faris Raouf Sent: 11 August 2005 11:17 To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] RE: GrandStream GSX-2000 strangeness Thanks to all who replied on this.
