How to use 3G Dongle Asterisk + Internet access via modem?

Question

Asterisk

There is a server on Ubuntu + Astrisk gateway via Huawei e150 GSM modem. Is it possible to somehow use it not only as a gateway but also to access the Internet at the same time? Not the main gateway, as a backup.

Answer 1

At the same time, no, it won't. I think that you can disable the dongle with a script - asterisk -rx "dongle stop now"or something like that - if the conditions for enabling the backup channel are met - and then connect to it as a modem. But, obviously, at this time it will not work as a GSM gateway.
