asterisk users - Aug 2011 - Wanted a modified SIP message body

Hello everybody,
I want Asterisk Server to send packets (SIP packets) to some 3Com telephones
with the text "TZ: 7200\n" (ie Time Zone = two hours) in the message
body
because 3com PBX sends this variable. I would like to know if I it is
possible to configure Asterisk to do it, and how.

have a nice day!

Use the  *SIPAddHeader(Header:Content)* application in dialplan. I don't
think Method specific SIP headers can be done via asterisk.

Hello,
I have been using wireshark to capture some traffic. I'm talking when the
PBX sends OK (200) connection accepted. 3Com PBX sends "TZ=7200\n" (an
much
more things) in a SIP packet message body but Asterisk PBX sends packets
without message body, it only sends variables in the message header. So I
want Asterisk to send packets with a message body and its proper content.

I've been looking for, sure spending my time. Modifying the source code is
not very realistic, but i have to try. The file channels/chan_sip.c seems to
have interesting functions like add_header(), add_tcodec_to_sdp(),
handle_response_invite(), handle_response(), also struct cfalias. I know C
programming but it's really hard to understand the code.

Should I ask in the developers list?

have a nice day
