in our lab for our call center agent phones , once we upload new firmware "9.3(1)SR4" and apply to different call center devices it successfully uploaded, but wehen we start to sue it and try to use "transfer" softkey it not working, so I will be appreciate all of you if you can help me out for this issue.

If this is in your lab environment I'd try to match the production as closely as possible including Media Termination Points (MTP.)

Hi Rizwan,

Are these phones using Headsets by any chance? If so, it may be this bug using that exact firmware;
