SV9100 and UT880 Phone ringtone

[LeeEng]

Asked in the past but have had no replys. i was wondering if any one can help. We are just setting up a SV9100 system with UT880 phones but i can't seem to get different ringtone for different calls. I can not find the setting for this in the phone it self. I know the PBX is sending different tones out as i have a couple of DT800 phones attached and i get the different rings on them.
Any help on this would be good.

Have you tried the access code?
Off hook, dial 720, 1 = ICM, 2 = CO, dial code 1~8 + spkr to hang up.
Dial 711 1 = ICM, 2 = CO, + 1~8 to listen to the tones first.
