Am I correct to assume that if you don't have a touch tone line, then it is not possible to dial out using the PSTN line? I have tried this without success. The result is a busy signal.
Also, I have tested this several times - when the obi110 is not receiving electric power (such as during a power outage) the connection to the PSTN line does not function (i.e. no dial tone). If I simply bypass the obi110, I get dial tone. Is there a setting to permit use of the PSTN line when the power goes out?
