A few days ago, I was advised by a relative that calls me long distance that they got a "phone not in service" message when they called me.
Since then, I've experimented and it seems that any direct dialed calls (both local & long distance) get through okay. But it seems that calls using a third party calling card when calling long distance to me, gets this not in service message.
Why are these calls not getting through? I've received this type of long distance calls in the past with no problem.
