Review on 📞 Enhance Your Business Communications with Grandstream GXP1628 HD IP Phone by Christina Potter

Great phone. Easy setup for a small PBX system with four external VoIP phone numbers using FreePBX on a Raspberry Pi microcomputer. Access the phone via LAN for configuration. In systems with many phones of the same model, individual phone configuration may not be possible and configuration can be configured for multiple phones using one file. This model is one of several Grandstream two-line phones that use select pairs of four lines. Very reliable with great sound. Firmware update directly from the Grandstream website using the configuration in the phone to periodically check for and download firmware updates; The prerequisite for this is Internet access on the phone; if it is used for external calls, it must already have Internet access. There are also tools to update firmware locally, and Grandstream has simple instructions on how to do it with a PC on the same network. For a small PBX system that can't or can't justify the cost of PoE (Power over Ethernet) to power phones, this model can be powered from an outlet and comes with one. The PBX must be familiar with the PBX software and the phones used. Once you get past that, it's easy to maintain and mod as the phone evolves, but requires occasional management and also requires security skills to prevent it from being hacked, taken over, and used by hackers to amass enormous phone bills exotic places like Nigeria. It is easy to prevent, but you must be aware that this can happen if the PBX system is not properly protected from outside hackers who have bots checking the PBX 24/7. The vast majority of issues I've seen others with these and other major brand VoIP phones are invariably due to this learning curve. This phone has two "SIP" lines, just like the GPX1625. The sister model GPX1630 has three SIP lines. The entire GPX16xx series is designed for smaller PBX systems. If someone needs more than three lines (GPX1630), Grandstream has phones with more lines in the mid-range and high-end. These phones are designed for PBX systems used in large companies with multiple employees. This is an extremely rare home with a PBX that requires a dedicated PBX server running on the local network. It has an RJ45 Ethernet jack instead of an RJ11 modular phone jack. If someone is getting phone service as part of a cable television service, these phones *will not* work because the cable modem has an RJ11 modular phone jack and is designed to work with the same standard PSTN (Public Switched Telephone Network) phone with what is known as "Landline" or POTS (Plain Old Telephone Service), usually single-line, the same type of telephone that has been in use since the introduction of the TouchTone telephone in the mid-1960s. .
