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

[ROZA, Ariel]

If you need to set up a SIP trunk between a CCM (behind a firewall with NAT) and a SIP PBX, is it _required_ to have SIP proxy functionality on the firewall?

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
