Grandstream GXP1625 Small to Medium Business HD IP Phone with POE VoIP Phone and Device

This is an excellent IP Phone. Excellent built quality and comes with all necessary accessories like power adaptor and LAN patch cord. I purchased it to use with BSNL WINGS. BSNL could not provide me an account in three months after taking rs. 1200 in advance. So I am using it with a free SIP service provider. It's call quality is extremely good, without any noise or distortion. It is also very reliable even on free SIP service. I am using it on Airtel extremefiber DSL line (40 Mbps up &10Mbps down), I have also tested it on 30 Mbps JIO Fibre sucessfuly. Be cautious about your service provider, because all providers do not allow SIP calls on their network. Alliance Broadband is such ISP in Kolkata. You have to request them to activate the service to use this phone in their network. I paid 3400/- for this GXP1625 which is quite reasonable.

It's good for a calling. But paid for every month.

This is not working, this series phone has a lot of bugs. Your SIP registration will wipe out each time you reboot your phone or the router. Need to reset each time to register it. Really annoying and now no way to get a refund as it has exceeded the time frame, just thrown it out. Happy now.

I'm using grand stream for more than a month. Voice and call quality with voip connection is great. It supports two sip accounts. Once configured, easy to use..speaker phone is amazing. Best product for home office. Works on LAN cable.

Having tried many IP phones (Avaya/Cisco/Audiocodes/Snom/Polycom) over the last 10 years, I can confidently say this is the most value of money IP phone (VFM) I have encountered so far. Therefore, I am slowing replacing all my office IP phones with grandstream phones. While I am on a call, the display even shows the codec that is being used. That is something I had never seen in any IP phone. As a VOIP professional, I highly appreciate it.

On time delivery . Good product

Just received the product Connecting was easy Tone quality and sound was excellent

Got 7 phones , working good so far no issue ,can recommend to anyone who are in need

Wer ein schnurgebundenes Festnetz-Telefon sucht und seinen VoIP-Anschluss mit SIP-Fuktion ausnutzen möchte, wird mit diesem günstigen Telefon glücklich. Natürlich sind Einstellungen erforderlich - Plug&Play funktioniert hier nicht. Eine ausführliche Bedienungsanleitung liegt NICHT bei, aber auf der Herstellerseite bekommt man alle erforderlichen Infos - zumeist jedoch in Englisch. Für mich ist es das erste Mal, dass ich mich mit diesem Thema beschäftige und ich habe das Telefon innerhalb von 15 Minuten eingerichtet: - Telefon mit dem Netzwerk und Stromversorgung (Steckernetzteil) verbinden - ca. 3 Minuten warten - Am Telefon den Button <Anzeige> drücken und IP-Adresse ablesen - IP-Adresse im Browser des Rechners (im selben Netzwerk) eingeben - An der Maske anmelden - im Auslieferungszustand sind PN und PW gleich: <admin> - Einstellungen des Netzbetreibers (z.B. Telekom) für SIP-Telefonie per Google suchen - Daten in der Webanwendung eingeben - fertig - Nun kann man noch ein bisschen Herumspielen und Kligeltöne oder andere Kontonamen zuweisen. Nun kann man das Telefon überall dort nutzen, wo sich der Netzwerkanschluss befindet. Auch an einem Switch oder WLAN-Repeater mit RJ45-Anschluss. Somit kann man größere Distanzen ohne Kabelverlegung überbrücken. Zum Telefon selber: Für den Preis ein solides Gerät mit einer gut funktionierenden Freisprechfunktion. Der Hörer liegt satt in der Hand und kann auch gut mal in die Schulter geklemmt werden. Einziger (theoretischer) Nachteil: Es ist keine vernünftige Bedienungsanleitung dabei. Aber wer ein bisschen im Netz googelt, wird sofort fündig.

This phone was bought for use with TekTalk VoIP service from TekSavvy and having used it for one week so far, it works like a charm! It's nice and professional. There are only three cords to connect to the unit: headset (coil), RJ-45 and (if Power over Ethernet is unused) the included AC adapter. It's possible to add VoIP settings on only the device itself, but I prefer the web interface Once configured, it had a clear dial tone and clear voice quality during calls. It is just as good, if not better, than a traditional phone line. I only have two complains with the unit: the coil cord is too short (it does accept longer third-party ones) and the unit needs an object supporting it so it won't fall. Otherwise, I am very happy with this phone!

Un sacco di impostazioni, stabile, display retroilluminato, ottimo rapporto prezzo prestazioni.

A good phone and quality too

After using Skype with a Skype phone for some time, I was looking for an alternative. This phone combined with the Sipgate Basic package is a great option. This Grandstream device seems to be good value with all the essential features that you need. It needs to be placed near your router or powerline adapter as it will need to be plugged into it directly. It also has a speakerphone option and support for a headset and can be configured for two SIP accounts. Ideal for use in a home office where you need an extra line, but don't want to pay line rental. If you have previously used a Skype phone or something similar, then this is a great alternative.
