Ring-Answer delays with Polycom phones

I am implementing intercom/paging in my environment.  I do so in my dialplan with a simple little context that contains the following:

exten => s, 1, SIPAddHeader(Alert-Info: Ring Answer)

exten => s, n, Page(SOME_DIALSTRING)

 

Now this works all fine and well, but my main problem is that as soon as the Page application takes control of the channel, the caller can begin speaking.  However, the phones always ring _once_ so the beginning of what the caller is saying can be lost.  Is there some SIP header I can use that Polycom phones will respect that immediately causes them to pick up with zero rings?

 

Thanks.

Apologies (I haven't been here in awhile and forget where things are) where exactly might I find these resources?  Can you link to the page(s) that contain them?

 

As usual, thanks for the assistance Steffen.
