I think many frum people have been in the situation of needing time-sensitive help with a halachic question, but not having access to their/any rabbi. What resources such as hotlines are available to such people for getting halachic information from a Torah expert fast? 

*I am not talking about formal piskei or even formal teshuvos (the distinction between "psak" and "information" is discussed somewhat [here](https://judaism.stackexchange.com/questions/77732/if-you-get-a-psak-then-hear-that-it-is-wrong-what-must-you-do/77786#77786)). Discussions about the halachic appropriateness of using a hotline for Torah information on an occasional basis--even a different community's hotline--or of whether you should go to a hotline rather than to, say, a published halacha summary, a primary source, or a local rabbi from a different shita--are not on the epistemic level of my question; about that, CYLOR, if you can ;)* 

*This question is subtly different from [this](https://judaism.stackexchange.com/questions/36454/consulting-a-local-orthodox-rabbi-if-there-isnt-one) one, because here I am talking about isolated, occasional incidents.*
