IP Phone using remote CUE via SIP

[asarlo]

Hello,

I have the attached diagram, and want IP phones located at the branch offices (Grupo 1, 2 y 3) to use the remote CUE located at the HQ (Central) via SIP. I know that CUE is a SIP destination I know that this can be do with H.323, H.450 transfer and H.323 translation to SIP. But I want a full SIP network without H.323 translations.

Can I do that, is there any reference that talks about this environment ?

Thanks a lot !

Regards, Anacelia

The proxies will then initiate calls toward thereal H.323 and SIP nodes in the Inside. All source and destination IP addresses are now of hosts within DMZ and Inside. Using PIX will help from avoiding H.323 translations

sorry, but I don't understand your answer. Can you explain with more detail ? You are talking about proxies and DMZs, and it seems is not about this issue.
