I was a bit surprised as Daylight Saving will be finishing here in UK on 31st October so how come phones gone behind a week earlier. I thought may be customer has got some messed up NTP settings.

Scenario#26 – Abbreviated Dial not working Cisco 7912

I was looking into this customer issue where they upgraded from Call manager 4.x to 7.x and almost all users on 7912 phone lost their speed dials. I checked the phones and CCMUSER page and found that the dials where there but they are not able to access it. Created a new Softkey template including “AbbrDial” at “off Hook” mode.
