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?
