Hi Community My Provider provides the following info when they supply a SIP trunk: . A direct connection into their network. i.e. they provide private IPs: . An IP address I must use for my FS box e.g. IP: 10. 42.0.66 MASK: 255.255.255.248 GW: 10. 42.0.68 . An IP address for their SIP server 10.42.0.1 I have setup a dual homed FS box (Windows Server 2008, latest FS version) NIC 1 - Internal LAN IP: 10.0.2.185 MASK: 255.255.255.0 GW: 10.0.2.253 NIC 2 - SIP Provider (WAN) IP: 10. 42.0.66 MASK: 255.255.255.248 GW: 10. 42.0.68 Windows complains about multiple gateways - which I ignore? I can ping internal addresses and the SIP Server When I fire up FS, I can register Xlite phones on my LAN. I can dial and hear the test IVR (5000) This means my Internal SIP Profile is ok. Now, how do i route a call out to the 10.42.01 SIP Server? Creating a gateway doesn't make sense, because I am not supplied a username/password? Any pointers would be most appreciated, I am sure I am missing something really simple. Roland
