In what way was my question not meaningful? Not enough details? Here's our current receive fax route: sender fax machine -> telco -> E1 line -> sangoma card -> asterisk
We're currently using free fax for asterisk. I have read that fax over voip is not reliable, but is it the same case for faxes going through dahdi channels? It's strange because I previously tested using another asterisk server to send fax using SIP to the receiving server above, and the completion rate is better than using an actual fax machine. >From the asterisk console I can see the receiving fax session running, but halfway it stops due to timeout or hangup. Below is a fax session output which was marked as failed: -- Channel 'DAHDI/i1/-4' receiving FAX '/var/spool/asterisk/fax/fax-65126150-1340338724-rx.tif' -- Channel 'DAHDI/i1/-4' FAX session '0'
