      Very helpful



      A popular choice for VOIP users that want multiline or multi account capability.

      I bought my Grandstream GXP2000 IP phone to use with Sipgate - one of the features I liked was that this can register with more than one VOIP account, so it would be possible to distinguish business callers from home callers. It does this job a treat. Audio quality is good provided the underlying broadband connection is good and provided that the LAN switches are reliable. It is worth making sure that LAN switches do not auto-negotiate speed or uplink, else drop-outs can occur.

      Just like a receptionist's phone there are separate keys for each of four lines, with associated LEDs so it emulates a key and lamp unit of old. The large LCD display is blue and white and tells you if the phone is registered, which line is active and shows called ID of incoming calls. Picking the handset up activates Line 1 but this can be switched to one of the others by pressing the relevant line button.

      The buttons are large and have a positive action, and there are 7 dedicated buttons for memorised numbers along the side which can be expanded with a sidecar unit. The phone has a loudspeaking mode that works surprising well, and on the back there is a 2.5mm jack where a wired headset can be attached.

      The Grandstream GXP2000 is powered via a wall-wart power supply or via power over Ethernet. My wall wart blew up after about a year and a half, though fortunately the phone still works after I replaced the 5V power supply with a generic replacement. If this happens to you note that the GXP2000 has quite a high current drain - the plate on mine shows 1.2A so the replacement supply has to be capable of that. Some forums seem to indicate the LCD backlight may dim is it is set to illuminate all the time. In practice most users will leave it at the default illuminate on keypress or incoming call.

      Configuring the Grandstream GXP 2000 VOIP phone
      Configuring a VOIP phone manually is never any fun because of the myriad of settings, though Sipgate have created a help file with the relevant settings for their service. The basics can be configured via the LCD screen, but it is easier to connect the phone to the network and let DHCP assign it an IP address, which will be shown on the LCD screen. Pointing a web browser at the IP number will bring up the login screen, and from there the detailed set-up of VOIP accounts for each of the four lines can be entered.

      This means that it is possible to use different VOIP providers and play off the different tariffs - some providers are cheap to call into but dear to call out from and vice versa - set up line 1 for the cheap outbound provider and line 2 for the cheap inbound provider and everybody wins!
