I'm going with option D as well. It's the only one that seems to address the issue of enabling communication between the SIP and H.323 devices.

Haha, disabling SIP in the external zone? That's like trying to fix a broken window by boarding up the entire house!

Hmm, option B doesn't seem right. Changing the domain of a SIP endpoint won't help in this case.

I think option D is the correct answer. Changing the interworking mode to On should enable the SIP and H.323 devices to communicate correctly.

Let's select option D then. It makes sense to enable the interworking mode to allow SIP and H.323 devices to communicate properly.

I think we should go with option D as well. Changing the interworking mode to On should do the trick.

I'm not sure about that. I think we also need to create a presearch transform to enable the calls to setup correctly.

I agree with Tamala. Changing the interworking mode to On would allow SIP and H.323 devices to communicate properly.
