I am trying to get my head around this issue, as it seems to be fairly intermittent and related specifically to the 525G phones. We are having troubles with certain touch tone menus when using the 525G phones, but not others. One of the places that I have seen it show up is with our local POTS Telco which is providing us with four Centrex lines which we are running into our UC520. The Centrex lines balance our incoming call requests if we have mutiple incoming phone calls on the same incoming line. In the event that all of our incoming lines are busy, there is a backup voicemail system in place to allow customers to leave voicemail for us on the Centrex which we can retrieve later. To do this, we dial a phone number and then input our password to get into our mailbox.
I have tried this with all of the phones that we have on the network currently, and everything seems to work perfectly except for the 525Gs. The phones that work are: 7921, 7937, 524G, CIPC. For some reason, the 525Gs are failing this task. Our receptionist, who has a 525G, has seen this show up in two ways:
1. While navigating through an company's autoattendant, she reaches a point where the numbers she inputs no longer seem to be transmitted to the system.
2. While inputting credit card numbers through an automated system (over the phone), the credit card numbers do not seem to be transmitted completely (i.e. not all of the numbers are being sent to the receiving system).
Any ideas on why this would affect the 525G phones and not the other phones on our network?
You found a bug. I reproduced your problem and reported it to the BU. The team is following up on this now.
I will post when I hear something (fix) related. Open a TAC case and have then reach out to the phone PM or me and we can save them some time, but log a case for sure.
Could you let me know what version of IOS you are running on the UC500? What firmware are you running on the 525 phone?
CSCsw89237: When accessing external voicemail, the phone intermittently fails to recognize DTMF.
That is fixed in the 7.1.7 firmware of the 525 phone.
I would recommend upgrading to the 7.1.7 firmware or the 7.2.5 firmware.
