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?
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.
