<p class="MsoNormal">Is anyone else using the AMI with res_fax_spandsp.so for real-time status?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am working on migrating a FAX application from res_fax_digium.so to res_fax_spandsp.so. I have noticed that the spandsp module generates far fewer AMI status events than the Digium module and the generated events contain less information.
For example when sending a fax there is no longer an event for every page. There are just a few FaxStatus events at the beginning and a couple at the end but they don’t contain many details. I can pull the required information from the Asterisk console by
running <span style="font-size:8.0pt;font-family:Consolas">fax show session <ID></span> but that output isn’t suitable for parsing.<o:p></o:p></p>
