Grandstream GXP2160 IP Phone | 6 Lines, 6 SIP Accounts | 4.3-Inch Color Display | Dual-Port Gigabit Ethernet with Integrated PoE

I run FreePBX in the cloud and have multiple phone number I use. In order to dial out from one of those numbers, I had to dial 9, 8, or some other combination of digits. I decided on the Grandstream GS-GXP2160 because it offers 6 SIP connections, the color display, and some various customization. Once I received the package, I was up and running in minutes. You can configure the phone via the telephone's keypad or via web interface. I opted for the web interface. I set up all 4 of my extensions and say they went green. Calling out was no problem, but I ran into my first hiccup. I couldn't receive calls. I opened up RTP ports 10001-20000 and SIP ports 5060-5061 to the phone. Now I was able to dial out, but from only one extension. I found that each account was assigned every other next available SIP port. Account 1 had 5060, account 2 had 5062, account 3 had 5064, and so on. I extended the range of forwarded SIP ports from 5060-5061 to 5060-5070 and that solved it. I continued setting up the phone and changed the time zone, set some wallpaper, and configured the weather. Getting the weather configured was a bit tricky. You need to look up your self defined city code. To find this you need to head to The Weather Channel and search for your City, State. It cannot be done by zip code. When you load the weather page for your City, State, in the URL there will be a code. For Redlands, CA it is USCA0923. Copy that code and paste it in the phone's configuration and it will instantly update the weather information. To view the forecast, push the first button on the home row left of missed calls. I poked around the other settings to see if there's anything else I needed to configure or customize, but didn't see anything that I needed to change so I called it good. Last night I did get hit with another gotcha. The phone kept ringing and it was from an extension which doesn't exist on my system. Some have called these ghost calls. What is happening is it is a hacker scanning your network and seeing if they can take advantage of any vulnerabilities on your system. I did some reading and found the solution is to enable Check Accept Incoming SIP from Proxy Only under Accounts > Account # > SIP Settings > Security Settings. I also enabled Check SIP User ID for Incoming INVITE. Another solution would to be to use non-standard SIP ports. But after making that change, I haven't received another Ghost Call.

allows for 24 extensions , or as in our case 12 extensions and 12 speed dial to cellphone call cell forward call receptionist now works for her money.... great for small office

Grandstream products DO NOT carry a manufacturer's warranty. Only resellers do. It's hard to tell what your warranty options are because of this. We've had issues with several of them. They have capacitors that scream bloody murder when plugged into PoE. Thankfully Amazon has replaced our bad phones. However... Grandstream has EXTREMELY responsive support, and they have been very receptive to new feature requests, and any other support requests. We are now running 16 of these phones, along with the GXP2130. The build quality is nice, the handset feels a bit heavier than our old phones. The screen is amazing, though the viewing angle isn't the best. Overall, it's a very nice looking phone, sitting on the desk. Color screen, nice graphics, the ability to customize the main background and screen layout. We plan to order another dozen or so. So far I've been able to get it to grab config files from our server, as well as our xml phonebook I do have a few complaints... 4 ring tones. I just don't get this. Don't worry, it's not like you can't customize them... but each phone has 4 ring tones. One, by default, emulates a ringback tone. You can change this via the phone's web interface to change the frequencies and make a different sounding ringback tone. The other 3 can have custom files uploaded. Here's where the problems begin. To make a file for the phone, you must take a file you get off the internet, put it in an audio program, convert to PCM wav, run custom ringtone program from grandstream, convert the file to a .bin file, put that .bin file on your TFTP server, then reboot the phone and it will download that ringtone. Multiply for every ring tone you want to "test". You then have to delete those ring tones from the server, because other phones might download them by accident. It's a lot of work just to change a ringtone. When you have multiple users, there's no way to give people options without it taking time. It would be a milltion times easier if you could upload a .bin file to the phone within the phone's web interface, and not have to reboot. The reboot alone takes nearly 2 minutes. The interface is a little slow in some cases, but it's not bothersome because it's a consistent slowness. Not as if it's bogging down at any point, but loading phone book screens and main menu can take a second or two. The reconnection of Bluetooth headsets seems to be a bit flaky. My current phone is rock solid and never has issues reconnecting to my headset, but this phone has, several times, asked me to re-pair the headset. (Current beta firmware 1.0.4.21 has fixed many of these issues, but is not yet released) I think the microphone of the handset makes the person on the other end, using the same phone, sound just a bit tinny. While talking to someone who was on a different phone, they sounded great. It's not a deal breaker, but I thought the other phones had a mic with higher quality sound pickup. After several months of use, I don't even notice this anymore. I also dislike how the appearance keys work. When you set one key as a BLF, the light is green 100% of the time the other extension is on-hook. Flashing red when that extension rings, and solid red when that extension is off-hook. I also see no indication of a possible orange (red & green combo) as we have on our current phones for extensions set to DND. With LEDs that are on 100% of the time, some could eventually fail. Some will fail before others, meaning that phones will have to be replaced. While this may just be an issue with our phone systems, it's something to consider.

I've installed more than a hundred of the GXP2160's and 2140's in the last couple of years. My SIP phone of choice for using with FreePBX and PBXact. Very easy to configure.

Perfetto

Solid construction. Great call quality, especially using g722. Gigabit ethernet is a big plus for piggy-backing a PC. The UI is relatively intuitive. People who've never used a VoIP phone have no trouble with the basics. For the price, this is a feature-packed phone that works very well.

Ce téléphone est vraiment excellent, rapport qualité prix au top. Nous nous en servons à titre professionnel (3 postes acquis) et vraiment très très satisfait !

Lo compré principalmente para poder hacer llamadas al extranjero a través de VOIP. El ahorro en costes es significativo, y el aparato tiene todas las funcionalidades necesarias. La configuración es sencilla y dispone de multitud de opciones y teclas que, a no ser que tengas unas necesidades amplias, no aprovecharás al máximo. Esta marca es muy conocida en el sector, y la calidad de este modelo es excelente. Muy muy contento con la compra.

Ich habe mittlerweile meherer GXP2160 zusammen mit einer UCM6202 im Einsatz und alles funktioniert hervorragend. Besonders gut gelungen finde ich die BLF Funktion, die kommt visuell sehr gut rüber und das Farbdisplay ist auch ganz hübsch.
