[cisco-voip] CUCM and Thirdparty SIP phone integration?

[garslan at secura.com.tr]

Hi to all,

Is there anyone who try to register third party SIP pone with CUCM from internet? Well here is the thing I am able the register a SIP device on local network or using VPN connection from internet, but what I need is put CUCM behind the firewall and NAT all ports to the outside to a real IP and try to register a SIP phone using that real ip address. When I try CUCm replies "Not Found" with the following warning "Invalid host or domain in request URI"

Thanks & Regards
