I have the same problem. While the OGM is playing (listening to the voice prompts) and someone presses a key to enter a mailbox, IVM doesn't detect the tone. However, if you wait until the end of the OGM, then press the key, it always detects the tone. I'm using a Jaton V.92 (Intel 536EP chipset). Any ideas on how to set the sensitivity? Thanks.
