I have a GL-XE300 with a builtin EC25-EUX modem.

Using this for network access works fine. - I’m also able to initiate calls manually by sending AT commands to /dev/ttyUSB3.

Now I want to connect the modem to asterisk. Asterisk is running fine and I’m able to connect to it using sip from my phone.

However I did not find a way to connect my modem, yet. There is the official package with the chan_dongle driver. - Unfortunately it always gives “SIGSEGV to asterisk for invalid read access”. - Maybe something in my configuration is wrong, but i assume it’s just not compatible with my modem.

There is also chan-quectel, which seems promising, but for this there is no package available.

Has anyone here been successful with getting EC25-EUX to work with Asterisk? (And how did you do it?)

you can re-use chan-dongle makefile and easily build chan-quectel friver just swapping source location and skipping checksum. Somebody with ability to test ie th device in hand has to submit it.
