<ul></ul><p>misc note: I've just ordered two GSM Fax machines (Possio Greta) which currently are available inexpensively. So if the time comes, we do have two machines.</p>
<p>Once synchronous CSD is supported, mobile-to-mobile fax might actually just work. The IWF on the MGW is only required for GSM-Fax <-> landline-FAX interworking.</p> OsmoMGW - Feature #5730: Fax over GSM supporthttps://osmocom.org/issues/5730?journal_id=263752023-03-17T09:53:59Zshadowcaster
<ul></ul><p>note: Possia Greta has Siemens module inside, for GSM faxing you may also consider to acquire Nokia 30 GSM Connectivity Terminal, which were more or less common back in the day. Perfect for faxing and CSD/HSCSD. Another pretty common device with fax/csd/hscsd support is nokia 9300/9300i/9500 communicators, they have enough resources to send and receive faxes as images.</p> OsmoMGW - Feature #5730: Fax over GSM supporthttps://osmocom.org/issues/5730?journal_id=263802023-03-18T21:06:17Zlaforge
