This is a signal that an analog phone can send into the system. Often called "flash hook", it is caused by a momentary press and release of the button on which the handset would rest while "on hook". Picking the handset off the cradle causes an "off hook" indication. Putting the handset onto the cradle causes an "on hook" indication. So, a "flash", or "flash hook" is actually an "on hook" followed suffuciently quickly by an "off hook". Many analog systems use this "flash" as a signal for conducting call transfers or switching between calls in a call-waiting scenario. > Thanks, > Daniela HTH, -Bob _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
