I have done many setups with Caller ID in the UK, I use this USB Modem which works perfectly (it is one of only a few which works with BT in the UK):
Anyway, I recently have a client in Italy and set them up using this same USB modem. Caller ID is active on their line but it isn’t working. I am just getting
RING when testing with Putty. I have tried all known AT commands:
AT+GCI=59 - Set country to Italy AT+VCID=1 - Turn on Caller ID AT-SCID=1 - set different type of Caller ID (I never use this in UK but makes no difference setting this for Italy)
This is not a SambaPOS issue because Putty isn’t showing the number - so I am not looking for help in how to use Caller ID in SambaPOS. It is a question to ask for advice of anyone else in Italy or experience with the phone systems there as to if there is a reason this USB modem does not work there - and if there is an alternative model I can use in Italy. Ideally I would prefer to use a USB modem over a dedicated caller ID device because of cost (and I have used USB modems on many setups without issue).
Caller ID works fine on the phone line, it shows the incoming number on a phone connected to the line.
