Subject: [PATCH] Fix remote CAPI (sent CAPI-Message length)
Without this change Bintec routers discard incoming remote CAPI
packets with the following error:
"ERR/CAPI: ERR(013217457) APPL-1:07 got too short CAPI message"
Note: Bintec user authentication is not yet implemented.
You need to disable CAPI authentication on your Bintec router:
-> "capiUserTable" must be be empty.
