# use the SDK to build the module:
# https://github.com/IchthysMaranatha/asterisk-chan-quectel
# The module is for two vendors, the Quectel-EC* and Simcom SIM7600. In
# preparation I bought one of each (EC25EUX and SIM7600G specifically), I don't
# really care if only one will work, then I'll just buy more of that specific
# vendor's model.
# now I noticed there is actually a Makefile for openwrt in the repo already:
# https://github.com/IchthysMaranatha/asterisk-chan-quectel/tree/master/openwrt
