Grandstream Distintive Ring Possible?

I’m trying to get a distinctive ring on my Grandstream GXP2130 phones with code like:

exten => _X.,n,SIPAddHeader(Alert-Info:;info=ring2) ; use either ring1, ring2 or ring3

But only getting the regular ring. Looking at Settings | Ring Tone on the phone I only see one setting for System Ring Tone. Are different ring tones even possible on Grandstreams?


Setting Up Grandstream DIstintive Ring

It was confusing to me that this is setup through Accounts | AccountX | Call Settings and not through the Ring Tone settings page. I am setting this up for a couple of Door Phones which will be at extensions 60 and 61. So matching to “[6]x” will fix things for me.
