Configure the GrandStream HandyTone 488 for use with GizmoProject

I got my GrandStream HandyTone 488 ATA a few days ago, and spent a few hours trying to set it up without much luck. Finally, with the help of a friend, I was able to get it to work using the following steps. - Connect the device to a router and a phone (follow instructions at http://www.grandstream.com/user_manuals/HandyToneQuickInstallGuide.pdf ) - Open an internet browser and connect to the ATA at http://192.168.2.1/ - Logon to the device config page with "admin" as the password - Enter the following settings in the "FXS Port" page. SIP Server : proxy01.sipphone.com SIP User ID : 1747xxxxxxx Authenticate ID : 1747xxxxxxx Authentication Password : myPassword - Just go with the default values for all other fields - Click the "Update" button and reboot the device ----------------------------------------------- I could get the ATA to work without the following changes to the router settings. In the router setting page, port-forward the foll...

Skype vs GizmoProject (continued....)

A friend of mine pointed out that a couple of Gizmo users disagreed with my assessment of Gizmo's voice quality -- check out http://forum.gizmoproject.com/viewtopic.php?t=8310 . Two questions were raised about my process of assessment... Was Skype running when I tried the Gizmo? : Yes, Skype was running when I initially tried the Gizmo. After reading the comments on the forum, I have tested the Gizmo without Skype running. Even without Skype running on my PC, Gizmo's voice quality tunred out to be inferior than Skype. Length of my testing : I have to admit that I've probably recieved less than 10 calls so far on the Gizmo; all my calls were forwarded by GrandCentral (not sure if that makes difference in the quality). After reading through some of the posts on the Gizmo forum -- I've decided to not give up on the Gizmo. In fact, just ordered a couple of GrandStream ATAs so that I experience the voice-quality with Gizmo on . I already have the Philips cordless Skype ...

Skype vs. GizmoProject

I've been using Skype for quite some time -- I have used Skype on a low bandwidth connection (128kbps) and a high band-width connection (6mbps), have had conference calls with multiple skype users, have had numerous video calls. And, so far I've been a fan on Skype's voice quality/clarity. A couple of my friends have been using GizmoPrject for a while. So, I decided to compare/contrast these two services. Here are my initial thoughts... Openness : GizmoProject runs on an open standard/protocol. So, this service is interoperable with other SIP phone services. Hardware that you may purchase for use with GizmoProject could be used with other SIP services (if needed). Skype is based on a clsoed/propietary protocol Voice Quality : GizmoProject's voice-quality is acceptable, but not great. There are (minor) delays, echoes, and the voice is sometimes broken. Skype's quality is way better. This was true even when I compared GizmoProject on the PC with Skype on the hard...

NetGear (model SPH200D) vs. Philips (model VOIP841) Cordless Skype phones

I've been using Skype regularly for the past 3+ years, and have liked the clarity/quality of the voice conversations. So, I decided to try the hardware-based Skype phones. I recently purchased the NetGear Cordless Skype phone (SPH200D) and here's my experience with it.The initial setup of SPH200D was easy; voice quality is good even with on a 128kbps internet connection. But I ran into the following issues with this device... The handset hangs each time there's a power outage (read a discussion about this issue at http://forum1.netgear.com/showthread.php?t=10453 for details on this issue). Since I plan to use this phone in a place that experiences frequent power outages, this bug is somewhat annoying. Plus, though, it's been a year since the release of the phone, this issue has not been fixed by the firmaware updates. The handset feels like a cheap piece of hardware Max Volume of the handset, even with the speakerphone turned ON is low The text on the phone &...
