Zoiper doesn't send SIP BYE when hanging-up a call.

Question

I'm seeing that when you hang up a SIP call received by Zoiper, it sends RTCP Goodbye, but doesn't send a SIP BYE.

Zoiper seems to accept a SIP BYE just fine and processes it.

But it won't send BYE itself.

Assistance most welcome!

Still the same, no SIP BYE

Guys, 

Which product you are discussing ? Please provide me with exact versions.

Answer 1

This was the Android App version of Zoiper.  Whatever the latest version was at the time.

I believe I found the reason for this while testing with a different client.  I believe that the far-end was returning an incorrect (or missing) "Contact" address in the response to the initial INVITE.

Hence Zoiper did not have a place to which it could send the BYE at call teardown.

So -- no fault in Zoiper I believe.  (Other than perhaps it could have shown a warning message?)
