I have a strange problem with my PGW 9.5(2) protocol patch version 70 running in signaling (nailed) mode.
I'm getting a call to a ported number from a partner and the PGW immediately drop the call with release code 28 (address incomplete). When I'm getting not ported number everything is fine. The only difference between the IAM messages is that the one with a ported number has NOA=8 and the normal call has NOA=3
Any ideas what a problem may be?
