Hey there.
We’ve got a grandstream gxp 2170, with 1.9.25 firmware. I’ve tried the beta firmware, but still get the same strange gui errors (not sure about lock ups). I’ve also tried 1.8 firmware, which is when we started trying to troubleshoot this in house. We switched phones as well, but the problems continued with the new phone so we haven’t swapped away again. The phone is currently hooked up to a 2020EXT extension board.
Basically, transferring a call will occasionally lock up the phone interface, allowing no input. The call is eventually ended due to timeout. Only a power cycle will bring the phone back to life, where it will perform fine for a few days and then lock up again.
Also, I noticed a lot of gui errors as I browsed the config: Under “Upgrade and Provisioning,” the upgrade button is replaced with: {el=firmwareUpgradeBox, rowid=0}
Similarly, the extension board settings are all code like the above, instead of actual values and buttons,and there’s nowhere to change any settings. ex: {el=Mpkrender, source=, rowid=1}
What’s causing this? I’ve tried factory resetting a number of times while flashing different firmware versions but the gui seems permanently messed up.
Is this a hardware problem with multiple phones? Or is something anomalous with our setup?
