Via Header not Required in Register request!

Hi,

Thank you very much for your help. I successfully created to and from
header with parameters.

Just a short intro, I am master thesis student trying to implement SIP
based
P2P application for mobile devices. As I am the beginner for both SIP
and P2P it would be of great help if this group could clarify my doubts
in future as well.

I'm trying to construct a register request without a via header. I 
think, there is no need for a via header in a register request. 

My problem is, that all of the four createRequest() methods need a Via 
(List) parameter. So I created any empty ArrayList and passed to 
The request. The request is successfully created without the param

But,

Shootist listener = this;
listener.inviteTid = sipProvider.getNewClientTransaction(request);

adding the Via Header to the request. I don't need the Via header in P2P
as there 
exists no special proxy or servers.

Please clarify my doubt.

Thank you in advance

Hi Jagadeesh,
                         Use the setParameter API , on your From or To
Header, you will get what you want, if you use it on the SIP URI, you
will get the name = value; parameter as a part of the SIP URI itself ,
i believe u need it on the From or To header, so use the setParameter
API wherever you want.

All the best, and one more thing , there is documentation for all the
API's , if you look up that, you can learn a lot of things you do not
know :-) .

Cheers.
Simith
