Cannot receive calls on SmartNode when PRI port is using the DMS-100 protocol.
Posted by Danny Staub, Last modified by Danny Staub on 15 November 2017 02:50 PM

When the SmartNode receives an incoming SETUP message from the PRI port, it returns a SETUP ACKNOWLEDGEMENT and then the connecting switch sends back a "Cause : message type not compatible with call state".  This is due to the fact that the DMS-100 implementation doesn't support overlap-sending, which is what is causing this SETUP ACK to be sent out.  To correct this, the following command needs to be entered in the ISDN interface to disable this behavior.

 

address-complete-indication accept set

 

Once this is set in the interface, the SmartNode will no longer send out the SETUP ACK.
