[pjsua] Verify response headers
Hi,
I would like to check/verify the response headers of a SIP INVITE request.
If the verification fails I would like to end the call. How can this be
done in PJSUA?
Thanks,
Kal
To explain my question in more detail:
(1) Client --[INVITE]--> Server
(2) Client <--[TRYING]-- Server
(3) Client <--[OK/200]-- Server
@ Step 3 I need to verify the headers of the 200 response on the client
side. If the verification fails, I need to end the call immediately.

Check for
case PJSIP_INV_STATE_CONNECTING:
In the:
on_call_state
callback.
Inside the pjsip_event you have access to the full rdata struct where you can check all the headers.

Hi Johan,
Thanks for the help. I will try to get that working. Related to this, I
also need to add headers to every SIP request AND response. What is the
best way to do this with PJSUA? The headers I want to add will be static
(same for every request/response and never changing). Is there a way to do
this directly? I also looked through the PJSUA callbacks, but I didn't see
one that could be used for this. Is there a callback mechanism with PJLIB
that can be used for this? What is the easiest way?

If it was only for calls and messages for instance you could use msg_data but if you want something that automatically works for all messages you can use a pjsip module.
You can check here for how I use it in another scenario:
https://github.com/johanlantz/pj-nat64
If you place a module for instance at PJSIP_MOD_PRIORITY_TRANSPORT_LAYER+1 you can use it to add or manipulate headers in all directions.

Hi Johan,
Thanks so much!!!
I implemented a module with priority PJSIP_MOD_PRIORITY_TRANSPORT_LAYER+1
to modify the headers and it works perfectly.
However, now I have the issue that I only want modify messages of certain
calls. Some calls in my process are normal SIP calls, and some will be
using a custom transport adapter and relying on this new sip module. How
can I know from the sip module what kind of call this is? Is there a way to
flag the call by adding some custom attributes to it? Or is there a way to
loop through all the attached transport adapters on a call and see if it is
attached and get state from it?

I have figured out a solution to the problem in my last post of this
thread but it requires a minor addition to the pjsip library. In
particular, I need a function pjsip_tdata_get_dlg() that is similar to
the pjsip_rdata_get_dlg() function, but that works on tdatas. This is
very useful to use from inside a module to know if a particular
outgoing request/response should be modified based on it belonging to
a dialog. I have attached a patch that implements this feature. I
would be happy if someone from the pjsip team could review it and
apply it if they think it makes sense.
Best Regards,
Kal
