Review on Grandstream GXP1615 Business HD IP Phone - Small to Medium Sized VoIP Phone and Device by Jun Bak ᠌

- There is no display backlight - not critical, but backlit would be nicer - The menu interface on the phone itself is not smart - with active use it can become dull. This is expressed in a set of numbers with a delay of 3-4 seconds, hanging calls - you have already picked up the phone, but in reality the conversation will begin in the same 3-4 seconds. Looks like a lot of savings on CPU and RAM. It is treated by automatic reboot once a day. : support has released firmware 1.0.420222 which solves problems with brakes and freezes, so you can exclude this minus, ate and live in peace - There are no normal warranty services, you can only hand over the warranty to a good supplier who takes the warranty on himself. - ONLY 2 lines and 1 SIP account, if you have Call Waiting enabled on the PBX, then transferring the call with 2 busy lines will not work - disable Call Waiting on the PBX so that users do not complain that they cannot transfer the call - It takes a long time to reboot, about 5 minutes, if he decides to ate the firmware - forget about him for 15-20 minutes - In some games, there is a clumsy wire to the tube, which eventually turns into an infernal tangle, they have a smaller coil radius
