Problem is, even with a traditional line, somewhere in the network I will almost guarantee that the call is getting converted to SIP. If the traditional POTS line is copper leaving the premise, it is most likely going back to a DSLAM or some neighborhood DLC where it is converted to IP. Most definitely is being converted to IP once it hits the local serving switch.
