fonny Posted April 5, 2013 Report Share Posted April 5, 2013 I have a problem receiving faxes witch have lots of white on the page. testfax.pdf is the original document. Document size is 210x297mm testfaxviaweepee.pdf is the document send with a hylafax client to hylafaxserver from weepee and delivered to weepee hylafax gateway. Document size is 215x298mm testfaxviasnomone.pdf isthe same document send with the same client to the same hylafax serverbut delivered to the snomone faxgateway. Document size is 215,9x279,4mm Any idea why the documentsize in snomone has 279mm width instead of standard A4 297mm ? Typo? For the rest everything seems OK. But the same page without that 1 line at the bottom is complete distorted when send by a hylafaxserver. testfax2.pdf is the original document testfax2viaweepee.pdf is the document send with a hylafax client to hylafaxserver from weepee and delivered to weepee hylafax gateway. Fax is OK but white space cut. testfax2viasnomone.pdf is the same document send with the same client to the same hylafax serverbut delivered to the snomone faxgateway. Fax is distorted. testfax2viapamfax is the same document send with the pamfax client to snomone gateway. Fax is OK. I tried with different layouts and always got the same kind of results. So bad line quality, server overload, etc can be excluded. It's enough to have a bit 'noise' on the page and the fax arrives perfect. snomONE is v5.0.7 MacOSX version testfax.zip Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted April 5, 2013 Report Share Posted April 5, 2013 During the FAX setup both parties have to agree on the parameters for the transmission. For example, FAX can transmit color pages with high resolution and many other interesting things. However our perception is that this has no practical relevance: Users that want to send high-resolution images use a scanner and send an email. That is why the snom ONE FAX implementation focus on that one standard FAX mode. One important parameter for FAX is the resolution. Interestingly, it seems that it does not make a big difference if you are using A4 paper size of US letter. However the vertical resolution obviously does matter. The PBX supports only the vertical resolution that everybody uses, well almost everybody obviously. Anyway, the resolution negotiation should be visible in the T.38 packets. It would be great to see the T.38 traffic, then we can see if we can change something so that the vertical resolution negotiation becomes clear.
