Hi all

I have a small doubt regarding announcements
When A(IMS) call B(IMS) ,after  T=X timeout ,if B didn't answer A should receive an announcement "the number you are calling is not available now, plz call again later"

My doubt is when A number,  is  mobile number(GSM) , and call B# (IMS) >> should A# hear the timeout-announcement message or not?

All of the above ,assuming A# & B# are registered ,available ,not busy.
Timeout for not-answering is 45 Sec

Thanks in advanced
