hey guys, wondering if anyone can confirm or deny a bug in the new 15.1(2)T IOS version, me and a buddy that has a VPN established use CME to talk to each other, he updated to this new IOS and i can no longer call him, get unknown number and double busy signal right away, he was still able to call me. then i decided to upgrade to this latest release and he wasn't able to call and vice versa. backed to the IOS i was using and he was able to call me again. I told him to back down as well to see if it would work again and he swears its my config when i know its not. So since hes being stubborn is anyone else able to replicate error, did google it but didn't find anything. Also don't have TAC support because i bought the router used, hoping someone on here has stumbled across this error.
