Save function Improvement

Hi all - Currently I have a formula URL that creates a child record and then it will save & next the record. 

Currently, it is slowing down the end user because the button is adding an activity following a phone call so typically the user will be in edit mode (not a problem) and will edit the fields one way or another ( update contact information for example ) and then they will press the button labeled "Spoke Live," which runs the formula URL mentioned in line 1. When they press this button, a pop up shows up asking them to save the record because changes were made to the record (Lead). <--- this is the problem 

Here is the code for the URL: 

var Text SpokeLive=URLRoot() & "db/" & [_DBID_XXX] & "?a=API_AddRecord&apptoken=XXXXXXXXX&_fid_10=" & URLEncode ([Record ID#])
& "&_fid_17=Spoke Live";

"javascript:{"&
"$.get('"& $SpokeLive &"');"&
"javascript:DoSaveAndNext();"&

"}"

What do I need to change so when the user clicks on the button, it will save all the changes that user made while in edit mode, run the voicemail variable, and then goes to the next record in their report. 

FYI - The code works fine. I want to bypass the pop up window that asks the user to save the changes. 

Thank you.
