When the user hits the transfer button, the caller is put on hold. The user is then able to call the third party they are going to transfer the call to. However, at this point the transfer button has disappeared from their screen and all they can do is resume the call.
I have tried resetting the phone but it makes no difference.
This is a phone that has been working for some time and the issue has come up today. We are using call manager 9.1 if that helps any. Please let me know if you need more information in helping to resolve this issue.

Is "MTP required" checked on the GW/Trunk the call goes out on? If so do you require MTPs for your call flows?

Thanks for the response. Sorry it has taken me so long to get back with you. The issue turned out to be related to the headset that the receptionist was using and a recent firmware update.

I opened a TAC case and found that my issue was a known bug found about a month ago - https://supportforums.cisco.com/discussion/12166856/problems-transferringanswering-calls-when-using-headset-79xx-phone-cscun26289
