Is there maybe a different Firmware also available (as you can see above mine is version 21.318.15.00.A highly affordable GSM VoIP gateway can be obtained using Huawei E155X or compatible USB modems and chan_dongle, providing both inbound and outbound calls on GSM/3G networks. Maybe it is indeed possible to activate voice for this dongle in the end. If anybody has different experiences/settings, I would be glad if you could share them. U2DIAG is not supported (or disabled?) to en-/disable the different USB interfaces.No clue if that might impact the voice capability/compatibility to chan_dongle.

Seems like Huwei might have changed the chipset to an 'own' implementation instead of licensing Qualcomm's. chan_dongle does not seem to parse that reply string further but bases its assumption whether or not voice is supported on the OK of the reply. That's where I got the impression that voice would be basically supported but might just be disabled. I could yet not find any Huawei-Documentation regarding the commands return values, the rest of the values seem to be the voice audio parameters. As you can see above, trying the enable command yet failed with 'ERROR' on the E3531.

This could indeed mean that voice is actually *dis*abled, as I read somewhere on the net that AT^CVOICE=0 would enable, AT^CVOICE=1 would disable voice.

the reply to CVOICE? -command returned a 0 as first value instead of the 1 above.

The foremost differences to an E1550/E173 were: ^GETPORTMODE: TYPE: WCDMA: huawei,MODEM:0,NCM:1,DIAG:2,PCUI:3,CDROM:4,SD:5 I had also tried some AT-commands manually (minicom on linux) to check its properties, here my findings: My comment on the E3531 was not denying the possibility that my stick might just have voice disabled. In my case, notĮnough resources and not enough skills. Get new modems at a low cost (about 8-15 u$s). So, if anyone wants to work on it, there is this an alternative to (with a cost) to make them work with the channel driver. I have no enough skills to modify channel driver to work with them,Īnd this chinese guys tell me that they can modify they firmware

Syntaxis in commands, chan_dongle dont handle it. The ^Cvoice feature still there, but due to a different Utility than huawei (voice enabled one) and works fine.īut, under linux, it uses a different set of instructions than So, with a friend, we decide to buy 4 of them. I found some chinese guys that manufacture modems voice enabled with Huawei modems uses a regular dongle chipset, so, i look for a clone. When i found this channel driver, i use it with some huawei modems iĬan found in the market in my country (e1753). I go a little far in the search of compatible modems and maybe my
