Re: [OpenSBC] How to modify From: Header

[<sa...@ER...>]

Hi Joegen

In this instance i am dealing with an ITSP that requires the From to be
*@192.159.100.100  and not *@themaninthemiddle.com .  I want to hardwire it
for now.  I was speaking to a vendor of SBC hardware who told me in all the
SBC's he is aware of you can make this charge in there admin interface.
Shouldn't openSBC offer the same basic funtionality, right out of the gate?
This is an increasing requirement from some ITSP when dealing with
peer-to-peer security.

Thanks for the info.  I was seriously thinking that i could make a hardwire
change in SBCSIPTrunkRoutingHandler.cxx

BOOL SBCSIPTrunkRoutingHandler::B2BRouteCall(
  B2BUAConnection & connection,
  SIPMessage & invite,
  BOOL /*ignoreRegistrations*/
)

Just for my info.  Could i make the hardwiring here ==
connection.AddRoute( routeURI ); ??
