I`m having really strange problem. I connect new provider, changed all gateway settings but i can`t take calls. While debuggins external and so as global no invite packet is showing up. I even tryed tcpdump - absolutely nothing. Just pings. Outcoming are ok, register is ok. If I switch to asterisk - no problem occures. Support says that server refuses connection, while another gateway works perfectly. I don`t know what to do... May be this can be usefull to. Prov have multiple realms on server and accepts only @myprov.com format. While to asterisk invite is thrown with sipid@myip. I tryed changing server hostname to ip, but still nothing. Here is my conf: http://pastebin.com/qKqAv38a <http://pastebin.com/mMrj33pN> Really appritiate any help.
