Hi there,

 

 I'm using VodiaPBX for the Faxes, FXS ATA gateways are connected to Vodia and fax machine is connected to that ATA, I'm using it since long time and never ever had any issue, suddenly couple of days ago faxes stop working completely. It's happening to inbound faxes, outbound looks good. Below are the logs as sample. Fax sent from 6317771792 to 7186438257 and it failed. If I move same ATA device to FreePBX it works perfect. I'm using Vodia Version 68.0.4 Please advise.

Anyone please.

In that trace the PBX is not involved in the actually FAX decoding, it just shuffles the FAX packets back and forth. My guess is that something on the provider side must have changed (the ATA has probably still the same software). At first glance the trace looks fine. We are now around 68.0.20 and soon 68.0.22, it might be an opportunity to make a backup and upgrade to a newer version.
