This device is intended to replace landlines. It connects to the wireless voice network and provides a dial tone to normal landline telephones. Problem is, there is no way to activate it. Device requires entering *228 [send] but landline phones have no [send] button. Called tech support--unable for them to activate it. Suggestion was to connect a landline with a remote phone that has a send button. SInce I have none of those will likely have to return it.
