Hi All,
I have noticed for a while in different forums that people have had issues with CLI display problems with the GXW-4104 and GXW-4108; particularly in the UK. I used to think that this was a software compatibility problem. Actually, the power supply quality is key for the CLI to display at all. Two new GXW-4104s have not worked for displaying caller ID on the newest firmware; 1.3.4.13, so I have worked with Grandstream to get to the bottom of it.
The Grandstream support guy that I worked with noticed that the line sounded somewhat noisy. I changed the PSU for an alternative type of the same voltage and power rating. The display worked fine. Nothing to do with the firmware.
We have two Grandstream FXO gateways - both would not display the CLI, so the PSUs supplied are just not suitable and are too noisy. I need to get in touch with Voipon to find out what has happened with regard to the power supplies for this device. Perhaps it is Voipon that pack in the power supply, rather than Grandstream. They are labelled as TPi model number TSA3-120125-WB voltage 12V current 1.25 amps. It is a switched mode type judging by its light weight and lack of internal transformer.
I hope that helps
