All of my clients are behind NAT! Unfortunately I can not put my captures here. The strange thing here for me is that: 1- Desktop can always REGISTER with all of my usernames. 2- My android phones can REGISTER with some usernames! For example if I have a 12 and a 17 username Android Linphone can REGISTER with 12 but not with 17. Kamailio will always return a 401 error. This thing only happens on Android Linphone.
I captured packets for both scenarios but nothing is strange about packets! How is this even possible?!!
