Originate cmd only adding Call-info to 1st Invite

I am running 1.8 and using Call-info header to cause phones to auto answer a page but when I try this using AMI Originate cmd I see that only the first (Originator) Invite gets the call-info header I specified and the others don’t - it this expected behavior or a bug?

Here is a simple Telnet version of my code that runs fine in that the 3 phones ring and can join the Meetme but only the Caller’s Invite has a call-Info header so the others do not auto answer.

Any ideas?

Working Telnet command:

Action: Originate
Channel: SIP/99906
Application: Page
Data: SIP/99903&SIP/99904,d
Variable: SIPAddHeader=Call-Info: sip:2.1.1.1;answer-after=0
Callerid: 999
Timeout: 30000
ActionID: ABC45678901234567895

The generated INVITES ( IP’s changed to protect the innocent)

Originator - call-info is present:
