barkleycr Posted September 21, 2010 Report Share Posted September 21, 2010 We have a pbxnsip server in one of our remote offices. We unplugged and took one of the phones to another office. We plugged into our LAN and opened up the firewall to allow all outbound and all inbound traffic to and from the sip server. The IP phone starts up, picks up a local DHCP IP address, and even has a dial tone. But we cannot make any outbound calls. Need further guidance on how to make this phone work at our remote office. By the way the pbxnsip server is not behind any firewall or anything. It has a public IP and is exposed to the public. Quote Link to comment Share on other sites More sharing options...
