GrandstreamGXP2135 8 Line / 4 Account SIP IP Phone, Inc PSU

This is the second of these IP phones I have bought, which are installed on a FreePBX system.Setup is OK if you know what you're doing, but as with most IP telephony kit there are way more features than generally needed and mostly for backwards compatibility.A quick start or FreePBX wizard would be a good enhancement to the web based admin/setup console.Will buy again and would recommend.

I'm sold, moving my phone line to VoIP.

This is a great office phone. It's what I use for all my business calls. It integrates very well with our 3cx system. That said, this phone was a bit of a nightmare to configure in comparison to some of the competitor IP phones... still - I like it!

The phone does exactly what I wanted and probably more! It arrived on time and in brand new unopened packaging.I'm running it 24/7 so time will tell on reliability, but at the moment it looks good.I have one line (Account) going off site using NAT and one Line direct to the local asterisk PABX, and it all just worked in 10 minutes

Works as expected

I've been using the same NEC switchboard for the business for over 15 years... the previous one exploded in a thunderstorm.This handset fits perfectly with the new Grandstream switchboard and this phone is fantastic, sounds excellent and does everything I want, which is a lot...(Answer machine, voice prompts, call queues, on-hold music... automatic day/night mode, automatic holiday mode... the list goes on...)

I use the phone on VoIP. Easy to program, easy to use and looks good. Keys are fully customizable. Great value for the price.

We did a rollout of nearly 200 phones with a new phone system a few years ago and used a less expensive phone (Fanvil X4) as our base phone. After replacing a relatively high percentage of problematic phones with this specific Grandstream, I wish we would have had the budget to deploy these from the very beginning.They are about twice as heavy, sounds considerably better, have a better web GUI, and physical layout.These also come with their own power cords, which is such a creature comfort when planning expansions they may or may not have PoE available.

Ottimo prodotto

Wunderbar funktionierendes Schnurtelefon, das mit etwas Googlehilfe nach ca. 2 Stunden eingerichtet war -verbunden per Lan mit der Fritzbox.Die Bluetooth Schnittstelle funktioniert einwandfrei - wird ein Anruf entgegen genommen und das Bluetooth Gerät erst nach Annahme angeschaltet, kann während des Telefonats problemlos das BT-Gerät als Ausgabemedium gewählt werden. Über das Webinterface können viele gute und auch sinnvolle Einstellungen vorgenommen werden!Insgesamt ein sehr gutes Telefon, was besonders zu Gigaset und weiteren IP-Schnurtelefonen eine güngstige Alternative ist. Sehr zu empfehlen!Einzig kleiner Kritikpunkt ist das sehr dünne mitgelieferte Handbuch - ohne Google etwas schwerer einzurichten.

compre dos teléfonos y uno no funciona, mi empresa es de atención telefónica y nos esta ocasionando muchos perjuicios, ya que no hay manera de comunicarse con el vendedor para efectuar un cambio.Necesito solucionar urgente este problema y no se como.
