Grandstream GXP2000 VoIP Phone
I recently purchased the Grandstream GXP2000 SIP compatible VoIP Phone and I have to say that overall I am very pleased with my purchase.
I have been using voip/sip software for several years and now that the prices of these phones have come down to more normal levels, I wanted to finally get rid of my land line which was costing far too much and make the switch completely to a very low cost and reliable sip service. I have used Voipcheap for many years and it was with this in mind that I chose this phone.
Firstly, the phone is exactly what one would expect from a high quality phone that comes equipped with high quality audio, in essence, it sounds great. There are no drop outs on my regular broadband service and the phone connects immediately regardless of country or destination.
On the downside, for those that are not very technical, the configuration can be a little confusing but the settings provided by Voipcheap did work from day one - the problem I had was some people found me to be 'offline' and that is a setting issue in the Grandstream software. To be precise, the setting for 'publish presence' has to be on and the setting to 'send keep alive' must be on. This last setting is the most important for what it does is send a small packet of data every 20 seconds to the server to ensure consistent connectivity.
After I had worked out that little gremlin, the phone has worked perfectly and I have been able to make and receive calls for free and very cheaply using the Voipcheap service. There are others of similar quality that provide a good service. I have been able to call home using a free sip account on Voipcheap, without restriction or limitation or even any money on the account and enjoy high quality calls all day.
I can highly recommend this product.
