You need Caller ID display support not voice.

For the voice feature you will need to update the firmware.
update the firmware and it should work.
Also ensure your telephone line supports Caller ID (double check with Telephone company)

I have installed the firmware and also got the confirmation from the manufacturer that the modem supports caller id.

I am unable to type in the putty terminal, it does not accept anything that i try to type. But it is detecting the ring when i call the phone.

Can you please help me with entering the commands of activating the caller id in the putty terminal.

can you check below link, there are detail steps/screen on how to test using putty

I used this command, after the second ring it says MESG=80080.

Is 80800 is the correct phone number?

That might be an issue related with this.

80800 is not the correct number.

I just checked with the telephone company, they say that the service is enabled. In support to that, when a call comes to my telephone, it displays the number from which the call is coming.

The POS application says that access to port COM3 is denied.

You have to close putty before running sambapos to free com3.

I’ve searched support manuals for you and found that +VCID=1 command enables caller id.
