If you have spark wireless with landline (landline phone plugs into thing with simcard and wifi).
1) The only way for multiple landlines is to run cordless phones to the 1 base station which is connected to the box. Some different brands can be linked if they are dect but you can only use uniden xdect with uniden xdect models, is that correct?
2) Why would the ringing tone (inbound call) on the uniden be different? Use to have a dual ring then pause between rings now just does ring-pause-ring-pause etc is there a way to change it or is this just the tone pattern which spark has for such a setup?
