    Hi,

    I'm testing the commercial functions with NFR licenced 7.1 system.
    I don't have T.38 compatible gateway at the moment so I'm trying the FAX server via internal calls but it's not working.
    I connected a regular FAX machine to an SPA3102 phone port (ver. 5.1.7GW and configured as described, http: //www.3cx.com/sip-phones/linksys-spa-3102-fax/ No longer available. New link: http://www.3cx.com/sip-phones/ ) and dialled extension number of FAX (888). After dial I heard just silence. If even now I started the sending on regular FAX machine, the result is "No Answer".

    Can I test T.38 FAX receiving (and sending via email) function this way at all?

    thanks,

    Hi,

    Have you setup the extension of the 3102 into which you have plugged in the fax machine. Make sure you use the phone socket not the line one. Also make sure you plug it into the right socket on the fax machine (line socket, not the phone one)

    From your description you are trying to send faxes from the fax machine to extension 888 but sending out faxes tends to be very hit and miss.

    For sending faxes from one extension to another internal extension I've found Zoiper works well.

    Hi,

    I tried voice call first certainly and it was successful.
    You mentioned Zoiper is not familiar for me, but I have an SPA3102. The 3CX recommends SPA3102 FXS to T.38 faxing.
    The questions remains same. Is able to send fax a T.38 compatible extension (SPA3102) to built-in fax server?
    If the answer is yes, why doesn't my testconfig work?

    thanks,

    Does nobody have experience with built-in fax server receiving internal fax message?

    you should be able to do this as long as both are not bound to the media server. If you call from the regular IP phone, will you get the fax beep?

    I didn't hear fax tone before but I switched off the conversation recording on regular fax connected extension and then I hear.

    Regular fax reported communication error. Its speed is 9600B.
    There is the server log below.

    Interesting.
    I do not have the commercial model of 3CX, yet I got mine to work with a simple old banger analogue fax machine, by simply plugging it in to my Draytek 2820 router's FXO port, then configuring the FXS SIP account as an extension off the system.

    Now saying it worked, it passed all the tests including the tone (extension to extension calling and answering, external likewise too, in and out), but - VERY big BUT, when the tone was sent it caused the router to lock up. Draytek tell me that their router does not handle fax through the FXS.... But i did not have such issues as above. Therefore it must be safe to assume for simple user capability all that is required is a compatable FXO/FXS router. Hope this helps in some way.

    You wrote about different case, the G711 faxing.
