18:40:53 <btracht1210> my fax to emails are failing.  I get an email saying "xxx-xxx-xxxx tried to send a fax document to your faxbox xxxxxx's Main Faxbox, but unfortunately it was unsuccessful." with "Error Reason: The call dropped prematurely"
18:41:14 <btracht1210> how would i go about troubleshooting?
18:50:24 <btracht1210> kazoo log: publishing fax_inbound_error resulted in completed. full result: {[{<<"completed">>,[<<"fax_inbound_error_to_email">>,<<"fax_inbound_error_to_email_filtered">>]}]}
18:51:31 <fink> email to fax or fax to email? usually call dropped prematurely is bad t38 negotiation or someone accidentally called a fax number and hung up... best way to debug is through freeswitch
18:51:53 <fink> i think you're looking at a fax to email issue
18:52:18 <btracht1210> fink: fax to email via Main Faxbox
19:03:35 <fink> ah, yeah, i'd start with checking your spandsp.conf.xml config, specifically enable-t38 and enable-t38-request (going to vary based on your carrier's ability to handle t38), then check fs logs
19:04:08 <btracht1210> in fs:  T38 REFUSE on response
19:04:27 <btracht1210> & [CS_EXECUTE] [INCOMPATIBLE_DESTINATION]
19:05:29 <btracht1210> enable-t38 & enable-t38-request are both true
