asterisk users - Feb 2011 - "intercom" SIP header being ignored by Kirk wireless handsets

Hey, Hi, All,

We have a few dozen of the Kirk (ie: Polycom bought this European brand) out
there & most all work very well & work very well with most all versions
of Asterisk.

But we have been tripped-up by one combination of firmware & version &
configuration variables. We are running Asterisk 1.4.23.1 (TrixBox CE). We are
running latest stable firmware on the handsets. Most other features on handsets
seem to work fine except this.

We followed the instructions in the deployment doc' which had us send the
"intercom" keyword in the SIP header, as seen here:

 -- Executing [*83 at from-internal:1] Macro("SIP/260-09cb49b8",
"groupintercom|Local/*83|q") in new stack
    -- Executing [s at macro-groupintercom:1]
SIPAddHeader("SIP/260-09cb49b8", "Alert-Info: intercom") in
new stack
    -- Executing [s at macro-groupintercom:2] Set("SIP/260-09cb49b8",
"CALLERID(name)=GROUP CALL") in new stack
    -- Executing [s at macro-groupintercom:3] Page("SIP/260-09cb49b8",
"SIP/279") in new stack


But this header seems to be ignored.

Has any one cracked this? Advice? Know any one who can be hired to crack this
for us?

Thank you very much!
