1. It wouldn't be posted here or anywhere else, it wouldn't even be reported on.

2. It would just be called a charity phone network.

3. Generally you don't need to self-segregate unless the outer world is opposed to certain values you have. When something is a Christian alternative, it's an alternative against some societal trend (porn being common). If it isn't incompatible with society, it doesn't need to segregate, so wouldn't; it would just be a phone network that donates to charity and it would attract all kinds. So an X phone network is automatically about the parts of X that are not commonly shared values among society, not about any arbitrary value X holds.

You could define the product according its proponents' values, rather than focusing on where they disagree with yours. Then it'd be less polarizing. But I suspect you'd argue that it's less informative to do that, perhaps even outright misleading.
