Tripe Combo to decode ISDN facility messages

ISDN Facility messages are often used when we integrate CUCM with third party voice messaging and PBXs. Decoding those messages are important while you troubleshoot issues like MWI. Recently I found Triple combo can do that ease. I was like wow! A small exe is required for that. MT.exe should be copied to the same folder path where you have Triple Combo.

Right click on a facility message and choose ‘Decode Facility IE’.

TC Display screen shows the decoded message. This is a message to turn ON mwi on a Cisco Phone for a new voice mail left on Nortel.
