[Freeswitch-dev] Missing Header in SIP Message

[Ronnie Beck]

Hello Freeswitch Gurus!

I have a simple problem I am hoping someone might be able to help me 
with.  I want to configure a SNOM phone automagically using SIP 
messages.  The process is described here: 
http://wiki.snom.com/Category:HowTo:XML_SIP_Settings
I have created a Freeswitch module which sends the appropriate SIP 
message to the phone but I have hit a small snag.  In order for this to 
work, two headers must be set in the SIP message else the SNOM will 
ignore the request.  Those are:

Event: snom-settings
Content-Type: application/xml

I have code which should do that but when I do a packet capture, I can 
see that the "Event" header is not in the SIP message that is sent.  The 
code I am using is listed below.  Is there something obvious that I am 
doing wrong?

According to the output I get in the Freeswitch console from my module, 
the "Event" header is successfully added to the event, however it isn't 
present in the SIP message.

Many thanks in advance,

Ronnie
