I wish to convert my android cellphone into a private pcbx (having the ability to carry out fundamental automated answering based mostly on speech and who is looking and performs dangle up). One thing requiring the ability of Asterisk.

There are quite a lot of tutorials on the right way to this by sip on rooted units, however in my case, I wish to do it utilizing the cellphone variety of my sim card which in fact is tied to a supplier that doesn’t give such choice (they gave sip credentials throughout years however that is one thing now terminated) so as to attain the general public switched community with none extra charges.

This wouldn’t be an issue on Linux as nearly each Linux appropriate cellphone modules have a bridge for Asterisk.
However for Android units, I learn (I put out of your mind the place) that not solely the modules designed for android telephones aren’t supplied with an Asterisk bridge, however that the majority the drivers controlling them are so closed supply that it’s not possible to compile a customized kernel utilizing them (that constructing continues to be potential however with out help for the modem) and that whereas all the things associated to telephony is managed by a daemon (I don’t keep in mind it’s identify), it must be patched by oem as a result of the kernel interface uncovered to userland is closed supply too and undocumented.

In order that no apps enable controlling the {hardware} cellphone moreover calling numbers and that even being root doesn’t change it.
If not, how can I carry out such superior utilization?
