Hi Kumar,

There is some code available for sending "MESSAGE" in the sipxstacklib. I
can't remember the filename, but you can search and basically replicate it.

However, I think you are trying some P2P here and I am wondering if PUBLISH
is the right approach in this case. I believe it should be NOTIFY since the
destination client should be able to interoperate with your client.

On another note, I hope your clients are not behind NATs since you may need
to do some bootstrapping in that case (sending message directly may work
inconsistently).
