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

[Ryan Ratliff]

Your nat device needs to be able to fixup the IP address information  
in the SIP messages or else you will get no-way audio (at best).

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
