I have some questions. Who defines the "Caller ID Method" and "Caller ID FSK Standard"? Does that depend on the voip service provider. Or on the phone equipment connected to the SPA1001?
The reason I ask this is because I have tried every "Caller ID Method" availabe on the ATA. And none works correctly. The "Bellcore" one is almost working. However it doesn't translate the "+" international prefix to "00". Analog telephones bought here shouldn't work with "bellcore". I am from Portugal (Europe). Instead one of the ETSI standards should be supported.
