Problems on iax trunk between 2 free pbx servers


I have problems with the way the call is received by one of the servers, which runs asterisk 11.0.
Asterisk is receiving the call from the from-trunk context, Ignoring the from-internal context specified in the configuration of the incoming peer
The context parameter has no effect, I need calls to come in with from-internal To be able to made calls through the outgoing routes of this server from server2.

¿Any idea to force asterisk to use from-internal context for this trunk?

Best regards,
