I have never been sufficiently religious to understand everything on this site without help from friends or family, but a question was asked by a non-Jewish friend that I was unable to answer, so I'm hoping some of you can help me, a conservative Jew, explain to non-Jews, what some of the views of orthodoxy are on the following question:
Suppose that I have a cell phone which is plugged in, turned on, and set so that the screen never goes off or locks. At the same time, I have a friend who also sets up his phone in the same way. We place a phone call before the Sabbath on Friday, which is set to speaker phone, so I don't have to lift the phone during the Sabbath. Can we leave the phone running for the duration of the Sabbath, so that we can have a conversation?
It seems that we are not interrupting the flow of electricity at any point in the process, as long as the phones do not die.
It doesn't seem that we are violating a prohibition against carrying.
It don't think that my cell phone is muktzeh, as it has been discussed in other questions on this site it can be used as a watch, and even so, I can use a simple stand to fix it, so that I do not have to touch it.
My goal is to give a good representation of these views, since my peers are almost completely ignorant of Sabbath prohibitions at all. Also, I appreciate any efforts to correctly tag this question. I'm not familiar with the variety of tags on this site.
