Question 1:
i'm developing a custom client sip with pjsip. This client when receive a call that can't be accepted respond with status 603. I think that freeswitch filter this status.

603 gets treated fine for me. I think we need to see more information - can you put a debug level log of the call with siptrace enabled (sofia global siptrace on) on pastebin (http://pastebin.freeswitch.org/) and then post the url here?

Chances are you're doing something in the dialplan that's answering the call, either before or after the failed bleg.

You said you had voicemail before... you can't send 603 back to the client and continue to voicemail because the 603 terminates the call.
 
Question:2
It's possible a custom Header pass trough in status response like trying or session in progress? I'm able to use custom header only on invite adding to invite a header with name like X-myheader. Any suggestion?

Yes, you can for 180/183, with the sip_ph_X- prefix. That puts the header on any provisional response.
http://wiki.freeswitch.org/wiki/Sofia#Adding_Response_Headers

For example:
<action application="set" data="sip_p_X-myheader=value"/>

AFAIK you won't be able to do the same for a 100 Trying since Sofia doesn't let FS do any handling at the required point. But have a try anyway just to be sure.

Hi,

I have two questions about FS:

Question 1:

This is an example of desired behaviour:
1000@localnet_ip                      FS(ip:localnet_ip)                                      1001@localnet_ip

INVITE ---------->
                                     INVITE --------------->                                
<-------------- trying                <--------------------trying
<-------------- 603                  <------------------  603
ACK ------------>                    ACK------------------>



The current behaviour of FS is:
1000@localnet_ip                      FS(ip:localnet_ip)                                      1001@localnet_ip

INVITE ---------->
                                     INVITE --------------->                                
<-------------- trying                <--------------------trying
                                     <------------------  603

<-------------- 200
ACK------------------>
<--------------------BYE

I'd like to avoid the current behaviour. It's possible a kind of message status path trough?
If the called party terminate the call before answering, FS send always to the calling partner 200 and BYE.
First thought was related to the voice-mail. Now voice-mail is disabled but the behaviour is the same.

Question:2
It's possible a custom Header pass trough in status response like trying or session in progress? 
I'm able to use custom header only on invite adding to invite a header with name like X-myheader.
Any suggestion? 

Thanks
Good Evening
