No, a DSL filter isn't requred. If using Fax, some people find that a DSL filter installed in the phone line from the Ooma Telo to the Fax machine, installed in the reverse direction, helps with Faxing.bmccollum wrote:If we're completely disconnecting and cutting-off traditional phone service from our carrier (AT&T), do we still need a DSL filter to be installed within the mix in order to use the Ooma Telo, or is the DSL Filter now no longer a necessity once the traditional landline service is disconnected?
What are the issues?bmccollum wrote:Could having a dsl filter installed make issues with using phone service through the ooma telo even worse?
If only the Ooma phone service is used, remove the DSL fliter and test.
I doubt that a DSL filter would make a difference with Delay. You may have Half-Duplex problems though. Half-Duplex problems can be caused by several things, but a defective Modem would be the first place to look. You could barrow a modem from a friend or relative, for testing, or purchase a Modem and try it, and if it doesn't help, return the modem.bmccollum wrote:Issues are very long voice transmission delays in conversations to where each party steps on the other person's words, and occasional popping and cracking during a phone call.
