We replaced a voice modem that worked fine and was able to receive caller id fine here in the US with a TELCTAUSB4 that we bought from you.
It won't give the caller id. We are using the same line that we know gives caller id. We have changed the "others" to all 1s for FSK but we can not get caller id. IVM version 4.02
Please tell us what to do before we send it back.
