Hello,
We have a Telrad digital 400 DB7 with an emagen voicemail system. I've had some users complain that when calling in to the auto attendant and dialing an extension number that they receive an "incorrect entry" message. I dismissed this for some time as user error, but the problem kept resurfacing. After some research it does appear that sometimes the first DTMF tone is not understood by the system, resulting in an invalid extension number being dialed. I am not 100% sure, but it appears to happen consistently at a specific instant during the greeting. For example:

"Thank you for calling...."

Right about between "you" and "for" if you push the button right then, it won't register... If the caller wanted extension 321 the system would only hear 21 and error out: "incorrect entry, please try again." This appears to coincide with the instant that the port changes states from Processing to Playing File on the system monitor. I can almost make it do it on purpose. Has anyone else had this problem or found a solution?

Thanks
