I haven't used app_Swift with Cepstral but iirc it wasn't deemed very

If you are not tied to the certified Asterisk version then perhaps try
using the latest Asterisk version (currently 11.13.0).

Have you tried contacting the app_swift developer and/or filed a bug at
https://issues.asterisk.org/jira/secure/Dashboard.jspa ?

You could try UniMRCP which sits between Asterisk and Cepstral replacing
app_swift: http://unimrcp.org
