SRTP over H.323 gw

Hi,

Does anyone have tested SRTP over H.323 gateways?

I'm dealing with a security issue and I'm thinking going through this.
However I've read this works only on IOS 12.4(6)T and CM 5.x for h.323
gateways.
Today I'm on 4.1(3) and still not comfortable to upgrade it just because
this issue.
I would like to hear some opinions about that. Does it work fine? How about
payload cryptograph: does it increase overhead over WAN?
How about DSP/PVDM usage?

Any information will be appreciated.

thank you
