This is the scenario:
Customer have Jabber for windows and deskphone model 7841 with the same DN (shared line).
When he is in a call and a second call arrives, the 7841 only beeps, but Jabber ring! He wan't do disable the ring when it is in a call.
I tried to change the Sound notification in Jabber without success.
I checked the option "Mute all sound when on a call" and nothing happens
CUCM v.11.6
Jabber v.12
Please, any idea? Regards
