I have been setting up my new Versalink C405. However, I could not find how one sets up the fax to use Distinctive Ring Pattern Detection (DRPD). My business landline and fax are on the same line with different numbers and a Distinctive Ring Pattern for the fax. How do I set up the fax to only answer the two rings pattern on the fax number. I have bnot been able to find anything in the documentation or when I tried changing the setup on the intraweb address
