[pjsip] Handling INFO request responses

Hi Benny,

I tested with two commercial proxies, one do not answer INFO request at all,
and the other answers with a 481. But both answer to BYE with 200/OK.

So I will wait on your fix.

Thanks

Hi Philippe,

I think you should first find out why the proxy sends 481/408, if the
remote dialog is still alive in the first place. I decided not to send
BYE because I would think that the BYE most likely will be responded
with 481 anyway, so why bother wasting another transaction?

But you're right, this is not strictly compliant with the RFC. I've
just added http://trac.pjsip.org/repos/ticket/488 to fix this.

thanks,
