Summary:                    Unable to overwrite SIP Header using SipAddHeader()
Description: 
I'm using the alert-info sip header to use distictive ringtone on Polycom
phone. Basically, the polycom need to see a specific value in the
alert-info field.

In Asterisk 1.2, I was using : Set(_ALERT_INFO=info=Custom 1) to set the
ringtone and to overwrite it later, it was using the same thing with
another value : Set(_ALERT_INFO=info=Custom 2)

In Asterisk 1.4, now I'm using : Sipaddheader(Alert-Info:Custom 1) but if
I try to overwrite it later with Sipaddheader(Alert-Info:Custom 2) it won't
work, it add a second header instead.

The polycom will now use the latest SIP Alert-Info header instead of the
newest.

sipaddheader does not check for duplicates, since you're allowed to have
multiple headers with the same name.
