I would if I knew how, or could find some example code that does
this. I did find
the BasicCall.cxx code, but I couldn't figure out how to use %s
string substitution,
and had asked list people this very question, but got no volunteers
to tell me how,
so I'm stumbling along trying things until I get it right.
testSdp.cxx --
sdp.session().connection().getAddress() = Data("10.1.1.1");
etc.
- Just because a test driver messes around with ASCII to
SdpContents conversion doesn’t mean it’s a good idea.
I'm sure it isn't, I just don't know better because I haven't found
out how to do things, so I'm having
to do a lot of experimenting, and am now (FINALLY) able to break the
program at key places with the source level
debugger and examine data. I just recently got to this level of
progress, and it's now made it a lot easier for me to analyse whats
going on.
For instance, in my application, my recipient has a SIP address
pointing to a domain that is NOT
the SIP server. They (my company) are not using DNS SRV, but I
figured out that I can
do this.... to.param(p_maddr) = "213.167.79.25"; to force it to
use this IP as the SIP
server I want. I don't know if this is the "proper" way to do
this, but it does work,
and I'm sending out the proper INVITE message and it goes to the
right server, but when
I ommitted this statement, it went to our web site, because the
code tried
to resolve the "domain.com" domain name, which pointed to their web
server, which
obviously not where I want to sent the INVITE request.
If you've read my earlier postings, you'll see my asking for the
proper way to do this.
- Read the Data class definition, it covers Data manipulation
(which you almost never need) adequately.
I have.... over and over. But I couldn't figure out how to specify
string substitution
by inserting an IP address into a %s format using the construct in
the BasicCall.cxx.
Because %foo is a C-ism and this stack is C++. Learn how to use
std::string, resip::Data is quite similar in many ways.
Care to tell me how? I would like to code this properly of
course... I only did it that
way because I couldn't think of any other way to do it. The test
code does not need
to do string substitution like I do.
You don't either -- see testSdp.cxx or SdpContents for the methods /
etc.
It took me a long time to find this, thanx for the tip. Did I reply
the correct way
this time? Sometimes my "reply all" doesn't work on certain messages.
