[asterisk-users] AMI status events with 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  fax show session <ID> but that output isn’t suitable for parsing.

Thanks, I figured that was the case but wanted to be sure I hadn’t missed a configuration option or something else.
