Many people use home answering machines that provide remote access. These systems rely on DTMF (touchtones) to switch from answering to playback mode and check for a security code to make sure it is you calling in. There are also systems that can direct a call to various mailboxes (or extension phones) based on a caller entering a digit after an announcement. Some home monitoring systems allow you to phone in and check the status of your heating system, check freezing temperature or for water leacks, etc. None of these things can be done without DTMF. If all you want to do is use the ooma answering machine, inbound DTMF is not required.dsinternet wrote:So what is the advantage of inbound DTMF?tommies wrote: Draw back, the hub hardware does not support inbound DTMF.
