Years ago, I set up Jabber in MRA with push notification for iphone and I remember we had to modify a timer somewhere so that the Jabber client on iphone would ring longer before going to voicemail.
It was written in the documentation "you have to modify x timer from 10 to 30 secondes" or something like that.
I'm doing the same setup now, everything works fine, iphones are getting the push notification but it ring only one time and then it goes to voicemail.
Was it the no answer timeout on the TCT profile ? I don't think so since I recall having to change it only at one place and not for everyone.
I've read the deployement guide but it has been updated today and I can't find the answer.

What should I do so the TCT profile ring longer.
Thanks
