Hello,
I am guessing you are using a TDM card (e.g. zap lines.) and probably have echo
issues and maybe just hearing your own voice back. But as for as the profanity
goes then it's probably some other person :) It is also possible that your
actual Bell Canada (or whoever the provider is) line is picking up other lines
and then you need a Bell technician to check the lines.
If your logs don't show anything and have a strong root password then I doubt
anyone tapping into your lines.
