Need help with changing variable regex

I'm trying to parse a message that is either empty or has a value. The message is \"phones\": \"\" and it changes when there's a value between the quotes for instance \"phones\": \"xxxx\"

\\"phones\\": \\"([^\\]+)\\" --> this doesn't parse after the second quotation.

\\"phones\\": \\"?([^\\]+)\\" --> this parses but includes the second quotation in the value column. 

I need it to stay empty if there's no value and if there's a value I need to pick the value without the quotation marks.
Would appreciate any assistance.

you can probably use "conditional mappings" to solve this.

Look for "conditional mappings" in "FlexConnector Developer's Guide".

With conditional mappings you can do something like

'if token = "\" map empty value to field'
