QUESTION How to replace comma in CALLER ID(name) in extensions_override_freepbx.conf

[Tom Clark]

I have modified extensions_override_freepbx.conf to send my iPhone the Caller ID name and number of incoming calls via the Pushover app. When the Caller ID name has an embedded comma, the text following the comma is missing when it is sent to Pushover. I've used STRREPLACE successfully to change spaces to their HEX equivalents, but I can't get it to replace the comma with the character of my choosing. What's the solution?
