We recently switched over our system to Cisco IP phones (7911, 7945 & 7965). We've managed to solve all the other issues we've had but this one is a bit of a head scratcher:
Several users in this system, with all three varieties of phones, have reported that they are erroring out when they are inputting numbers into automated phone systems.
One person continued getting an invalid number when dialing "2" for English, another person got the same response from inputting her bank account number over and over again. In many cases, the numbers had to be reinput several times before they went through. No matter the number(s) input, no matter the number dialed, they are getting the errors. But not everybody. I've had no problem with automated systems, many of my co-workers have had no problem.
At first, we assumed it was user error but too many people have come forth and all with the same story: automated system, can't access whatever it is they need to access (some personal, some work).
We haven't heard of any issues dialing numbers (to call someone) and my guess is because the numbers you are dialing for a call appear on the display, whereas the additional numbers you would dial after reaching an automated system do not.
Our best guess foor now is that it has to do with the tone of each number and duration of the tone. On our old system, you could press a number one second or ten and it would carry a steady tone. On this system, the tone is a specific length of time and then disappears. I'm unsure of how, if there is a way how, to configure the tone but that would certainly be a help.
We are using CM 6.0.1
I searched through the forum quite extensively and found no other similar issue to this, but I am hoping it is something that can be remedied.
