I got 2 units, the hardware supports voice, but the firmware have not it
enabled. E173 rev s-6 (firmware versions start with 21..). For test
purpose only and project feedback.
Units are "huawei" oficial, not form any provider, but huawei support
don't provide firmware for this one.
(sorry if the question is not directly project related, feel free to
ignore it if go against group policy)
Thx
dc-files.com have only an old firmware (for the first E173), not for
this revision (when i try to flash it gets error)
