Anyone know the DTMF specs for various Partner phone system functions? I'm trying to simulate the "Recall" feature (F03) using a Dialogic D4/PCI card. Actually that's all I need. I need to send a hookflash to the CO line from a PC based IVR system.
Actually I may be way off base here - I'm assuming the phones use DTMF or some type of tones to tell the processor what to do when a feature button on the hand set is pressed, but I don't actually have a partner phone to test that theory.
