You are going to fill up your history file and it will become practicly useless for its intended purpose that is to record historical events, like errors, backups, etc. Using OTM has the function to collect all CDR, traffic. Then on top of that it has the tools to run reports on CDR or Traffic. If you dump to history buffer or Procom then you have to come up with a way to sort through that info. Get ready to open your NTP's and be prepared to try to figure out what every line entry is what its actually telling you. Nothing wrong with that if you want to try to become expert at ready these messages just harder than it worth, Especially when you already have a tool like OTM that does everything for you. Just my honest opininon.
