[Freeswitch-users] Calls to the external phone

Hi. Using the default configuration. There are internal and external real IP. I have several registered account from the internal network. I want to connect remote user from Ethernet. For this added external real IP to the external sip profile (param name="sip-ip" and param name="rtp-ip") and copied the directory/default.xml in directory/externa.xml which changed the <domain name="external_IP"> Now remote users can register and make calls. But there's a problem: No one can call to this external user. Tell me, what am I doing wrong? Thank you -- WBR, Dubrovskiy Viacheslav
