Hi Nicolay,
I don't think there is a print in the Freeswitch logs for the the 
Calling Name, so you will not see a mention of "sip isdn name 
interworking" in the logs.

The Calling Name is encoded in Display IE in IA5 characters based on Q.931.

Can you enable Q931 trace before making an outbound call and I can check 
whether there are any problems with the encoding?

To enable Q.931 trace:
ftdm sangoma_isdn trace q931 <span name>

And add this line in your dialplan before bridging to freetdm:
<action application="log" data="caller_id_name:[${caller_id_name}]"/>

Make an outbound call.

And send me the Freeswitch logs.
