Hello
i have a linksys papt voip box when i try to config it is not ringing my landline phone, all the corrected ports have been forwarded. However with i use the softphone (freephonelines) one it works also tried a third parties (Zoiper5) and it works. i have isolated the issue to the voip box. for configuration i used the pdf form this forum the the that was updated recently.
also in the settings once someone calls their info displays here where it says line one confi but the phone is not ringing and there is no dial tone once i pickup.
edit: got it fixed ip was temp banned and after an hour it went away
