Grandstream SIP GXP1630 Entry HighEnd

I needed this voice over internet phone to replace an old-school landline. It has many features related to office use that I don't need (forwarding, conferencing etc.), what I do like is that it resembles my old desk phone in looks and operation. It has a speaker phone built-in, for example. Digital setup is challenging - make sure your service provider is familiar with the phone you purchase, so that they can provide a guide to the settings.

E' un buon telefono di buona fattura semplice da configurare e compatibile anche con PBX VOIP non Grandstream.

El producto se entrego antes de la fecha, en excelentes condiciones y funciona muy bien.

Maybe...Do you know what an IP Address is?Do you know what SIP and VoIP stand for?Do you know how to configure a router and DHCP service?Do you know how to update firmware by downloading the correct file for a model number from a web site and then patiently waiting for it to finish without poking it?If the answer to the above are "Yes, absolutely" then you're set.If you're looking for an easy phone to use with Vonage or Skype, or some other thing that you think is a VoIP service...If you're looking for something to use with your cable company's VoIP system...If you're not certain what BLF means and don't care...If you think manuals are for wusses...... Then you should probably skip this. It's not worth the hassle you'll encounter and the return you'll have to do when things like attaching the stand incorrectly or failing to read one of the six pages that explains to flip over the tab beneath the handset for wall mounting cause endless frustration.This phone (and phones like it) are primarily intended for professional telecommunication contractors who set them up for a living to install and configure for offices. This is very much not meant for end-users in the normal sense of the word.Most critical first parts:-> There is no warranty for end users.-> There is no technical support for end users.If you are buying the phones from here, the warranty is provided to the reseller, not to you. The same with technical support. The only information provided is the digital information online. The quick-start manual is meant to allow a professional installer to know the variable specifics related to this phone (physical and data specifics) and then everything else about SIP and such is up to them in general."But Kit, why would anybody want to buy this phone then?!"I'm so glad you asked!People would want to buy this phone if they know how to set stuff up and don't want to deal with ordering 20 directly and having 19 spare.People who want to tinker and consider it a project would buy this phone.Professionals who want to prototype one or two to see if the phone is a good value for their business would find this a good way to grab a small quantity to test.There is definitely an audience. Knowing if you are in it is an excellent start to ensuring that you do not have heartache with this.Are you the proper audience for this phone? Then read on!Grandstream caught my attention back in 2014 when I needed to set up a phone system for a school on a shoestring budget. Most other VoIP phones (Cisco, Polycom, etc) are very pricey and when you're putting phones in classrooms with students, you are pretty much -guaranteed- to be replacing them frequently. Given the choice between a broken $90 phone or a broken $40 phone, Grandstream was a great deal. Damaged because kid knocked it off is not covered by warranty after all. Yaelink was considered as another option, but even there the most base unit was substantially more expensive.The GXP1630 is more what I would call a High End Low-end phone. The GXP1xxx series is considered the entry level set and the 1630 is at the high end of that spectrum. Gigabit switch, PoE, three SIP accounts, and a good selection of BLF buttons makes this an excellent option for a VERY inexpensive phone that needs mutli-line, multi-account capability and needs to run on a single drop with a computer adjacent. 45 and sixty degree desk position and wall mounting make it flexible, while the design of the display gives it a higher class feel than the substantially-less-expensive GXP1615.Build-quality-wise, the phone is sturdy. The handset is weighted to give it a good heft and the plastic construction is rigid and substantial. Buttons have a good amount of travel and are sturdy. Indicator lights are visible from various directions and the BLF buttons have a smokey lens area that allows the button to look more solid black when not lit.Depending on the codec on the phone and the codec chain in general, the latency can be extremely low. G.711 has barely above packet duration latency. Encoding, encapsulating, and transport has very little overhead. Other compressed codecs suffer slightly more latency however as the phone cuts costs by reducing computing power among other things.Sound quality is very decent both receiving and sending, and of course subject to codecs in use in the chain. If you know SIP/VoIP, you know what I'm talking about. If you don't, suffice to say that if you use G.729 from the phone to the PBX, which they transcodes it to G.711 to hit the trunk, which sends it to another system that re-transcodes it to G729 again (Or, *shudder* G.723.1), it's going to get messier and messier every time it's changed.The phone can run off the (shockingly tiny) 5V adapter or off PoE, and it's fully able to be auto-configured via DHCP and the PBX. With a small bit of preparation, deploying hundreds of these is just a spreadsheet of MAC addresses and configuration values away.In general, this is a very nice phone. That being said, there are a small handful of things that are frustrating about it.- The volume control rocker isn't a rocker. There is no pivot in the center, so both buttons can be pressed simultaneously, including by accident.- Grandstream has a history of intermittently-poor firmware. Any unit you get should be checked for the current firmware version and upgraded as needed for reliability and stability.- User education is complicated by the icon labels on function buttons. This is a great idea for the concept of multiple languages, but trying to describe to a user what button to press can be a pain. "Nobody can hear me!" "The phone is muted. Press the mute button again." "Oh, you mean the one-legged spear minion button?"And last but definitely most annoying: The paper insert for the BLF area is an annoying munge of rounded corners and cut in notches. Where other phones (Even in the Grandstream lineup) can easily have BLF data printed and cut out with nice straight edges, that's not possible on this one. You're pretty much stuck with hand-writing data on the existing supply of inserts or fudging it or buying new ones if they run out.In general, if you need numerous SIP accounts and/or a Gigabit phone with separate power and an internal switch, and want to not break the bank, this is the model to go with. If you're looking for a very inexpensive phone and don't need the Gigabit or switch, and only one line, the 1615 model is exceptionally inexpensive and still a decent quality basic VoIP phone, with a full setup surviving even the rigors of a grade school.

Cada vez que compro un aparato nuevo, sea de lo que sea, me estudio bien las opiniones, las características y las comparativas que encuentro por Internet, porque no quiero meter la pata...Así hice con este aparato. Me estudié más de 10 teléfonos, de diferentes marcas y modelos. Y finalmente me decidí por este Grandstream GXP1630 porque me permitía tener 3 líneas diferentes y porque todas las demás características me parecieron útiles.Después de comprar y probar el primer aparato, me compré un segundo, un tercero y así hasta cinco teléfonos del mismo modelo. He repetido porque creo que he acertado con la compra.Espero que os sirva esta opinión.
