Hi Jice

Thanks for your answer. I'm trying to replace another SS7 controller with YATE, and everything works OK, except for domestic calls. When the other SS7 controller sends IAM, the provider sends ACM in near 3 or 4 seconds, but when YATE sends IAM, it takes near 15 seconds to receive ACM. I check diferences between YATE's IAM and the another controller, and there only 3 differences, one of them is the USI, that is not sent on the other controller, but YATE does.
The other differences are:
INN denied in YATE.
Screening Indicator--Value 3 in YATE, Value 1 in the other controller.
Do you ask this question because the same behavior?
Thanks again.
