Description (partial)

Secure phone (V.32) modem relay may fail to connect intermittently when connecting to modems that are sensitive to a glitch in the signal between the end of answer tone and the start of modem handshaking.  This bug does *not* affect non-secure phone modem relay (V.34).

This problem happens randomly, but will only be a problem with modems sensitive to a glitch between answer tone and modem handshaking.
