    I recently switched from Verizon to T-mobile and had the same problem on multiple lines. I also noticed that it happened almost always when I was at home, but almost never when I was at work 20 miles away. I called T-Mobile and here is a list of solutions we tried:
    1. Turn off keypad tones. Phone > Settings > Call > Ringtones and Keypad tones. This solutions might work, but it didn't solve the problem for me permanently
    2. Increase length of DTMF tones. Phone > Settings > Call > DTMF tones. This did fix the problem for me for manual dialing during a call, but if I have a contact setup to dial a number after a pause it failed half the time. Also this option seems to be locked for Verizon Galaxy S5s, because it does not show up most of the time, I am not sure how I was able to change it, I just played around within the settings and it showed up.

    I found solution 2 only last night, before that I spoke to T-Mobile tech support multiple times and didn't get a solution. Finally I spoke to a network engineer with T-Mobile and his explanation was that since the Verizon S5 does not support all the same bands as a T-mobile phone, there is a chance that at home I am in an area which uses an unsupported band and the DTMF tones are not working. I am not sure how accurate that is.

    If anyone else has anything to add to this please do since the problem is still there with both my phones.

    I saw this on another post and it works. Go into Settings, select Applications and select Contacts. Then select Contacts to Display. Temporarily turn off Contacts by selecting Customized List. Now try the Keypad with voicemail. It worked for me. Then I restored contacts and once again the Keypad works with voicemail.
