For the records and others who may run into the same problem:

Problem is solved. The external Hylafax was configured in a way that it was sending ath1 after initialization. After changing to ath0, modems are no longer considered as busy.
Look for "onhook" in Freeswitch CLI after hangup.

Best regards

Hello,

according to the Hylafax wiki page we could set up 4 modems with Hylafax. We also used termnetd + interceptty to extend the modem interfaces to a remote Hylafax server.
The interface works outbound: Fax from Hylafax to Freeswitch works.
However bridging an incoing fax to modem/a/a fails very often.
I we want to send a fax, right after the processes are started and modems are connected, it always fails with "no modems available". The same happens if we explicitely set an interface number, e.g. modem/1/a, which is available at that time.

However, after waiting a while, we can get a call through, an available modem is detected. It seems as if modems are detected, but they are not considered as available. Just after some time they may be released, in my opinion.

My questions:
