Hello *,

I have an All-In-One intranet server and usualy a seperated
as default gateway, which connect me using HSPA to the internet

Now I have installed an Huawai K3765 on my , installed “pppd” +
usb-modeswitch and removed the default gateway to .

OK I can continue surfing trough the and is now using
the Huawai as gateway to fetch mails and send mails.

Also I have installed “sms-tools” which I use in combination with my
installed “courier-imap” server to send and receive SMS trough a Siemens
MC55… but this I like to drop now in favour of the Huawai Stick.

And at last I have installed “asterik” which allow me to do phone calls
using an IP-Phone connected to my switch of “kphone” on my workstation,

Now the problems with the Huawai USB-Stick:

Since HSPA is working and I get an internet connection, I am wondering,
how I can get the SMS and telephone part running, exspecialy the Huawai
USB-Stick is designed for parallel use of UMTS/HSPA and SMS/Voice

Can someone help me please?

Note: I am in Germany and use O2/Telefonica Prepaid SIM cards.

Thanks, Greetings and nice Day/Evening

  • Hi Michelle,

    Perhaps i’m not understanding your question correctly.
    an umts/hspa-modem, But now you want to use sms/voip directly?

    afaict, you can only use the voice/text-services from asterisk over the
    IP-layer offered by your modem.

    If you want to use the GSM-chip directly, you need (parts of) another
    project: not asterisk, but openbsc. But i don’t think that they are yet
    capable of communicating to Huawei-hardware (i have one myself)

    You got a working IP-connecion ontop of the underlying gsm-stuff, and
    have access only on anything on the ip-level, not to the protocols
    underneath, i think….

    As side-info, if you have openbts or openbsc up-and-running, you do have
    directly access to the gsm-stuff (and above), but you need dedicated
    hardware, like a nano-bts. And these are huge and costly compared to a

    There are some devices created by “udev” and it seems I have to tty and
    a sound port or something like this…

    Do you mean with the “tty” and the sound port?

    I think not

    I know with FreeSWITCH it is possibel, but FreeSWITCH is not in Debian
    nor is it stabel enough.

    (I have Asterisk and FreeSWITCH installed to do testing)

    I have this now installed in my Kernel and tried to configure asterisk,
    but if it connects, I can not more use the UMTS IInternet connection.

    However, I can not get a voice connection…

    Is there a working config, which let me use

    1) UMTS/HSPA Internet
    2) Voice Calls
    3) SMS

    at the same time? Currently I use the “Vodafone EasyBox 803 A” and I
    like to get rid of ths pig as fast as possibel!

    Normaly the USB stick provide the UMTS/HSPA channel, but it is blocked
    by Asterisk and I do not know why. Maybe because asterisk try to reserve
    it vor Video-Telephony?
