Asterisk fax pdf to tiff4/9/2023 Its roughly 204x98dpi, “super fine” faxes are at higher resolutions. Make sure your tiff is at the right size, there are many sizes supported by fax machines but 1728×1078 is probably the most common (and is at standard resolution).Some remote fax machines and PSTN lines can also be of low quality so while you may eventually be able to get good success overall some machines may prove to always be a challenge.A quality carrier is extremely important. Carrier/Provider doesn’t support T38 well or is poor quality for standard codecs – Some carriers end up using several other carriers and the more carriers a call goes through or the lower the quality of carrier/route the harder (and sometimes much harder) faxing can be.A T38 gateway (or multiple) end up inbetween each transcode is going to hurt the chances of success.Remote machine doesn’t support T38 (properly or at all), this is going to make things worse and is obviously common with PSTN machines.Or check your installed codic “PCMU,PCMA” inside freeswitch. If it not received check your sample.tiff format it should be compatible with tiff fax standart mode. Originate sofia / gateway / 90XXXXXXXXXX / 909999999999 & txfax ( '/path/to/file/sample.tiff' )įollow the log result you will see if Fax has been received successfully.
