try to get him to recognize the ringtones by the caller.
hence (Matching Incoming Caller ID)
6400 ringer z
6401 ringer y
6402 ringer z
Thank you for your thought.
There are hundreds of different outside callers, so this would not work.
Also, the Ring Group ID (6400, 6401 & 6402) do not appear on the screen of the phone nor in the Invite Message sent to the phone. (viewed via Wireshark)
What you might try is to use an IVR in conjunction with a ring group. Not knowing more about the routing, you might try going to an IVR first that has no entries and a quick time out that defaults to the desired ring group as a default destination and in the IVR change the alert info accordingly. I have not tried this, but it may work.
I tried this and it does work…but only with the Bellcore-dr1 through dr5 ringing signals.
I set the quick time out IVR’s Alert-Info to Ring 1 and it shows up ok in the Invite Message to the phone
like this —>>> Alert-Info: http://127.0.0.1;info=ring1
I have the “Match Incoming Caller ID” / “Matching Rule” set like this http://127.0.0.1;info=ring1 and “Ring Tone” set to Custom Ring Tone 1
But the phone rings with the default ring tone.
I did download the 3 Grandstream Ringtones and verified they were in the phone.
I am getting close to a solution.
Any further ideas???
