Re: [Linphone-developers] commit c5b17b4aa388c6d3b0b14e8ac96fe1b9a07ce2f7

Ok I understand, the cancelation comes from the remote endpoint. 
I think the if (code==487) is useless. Probably something we introduced
accidently without clear understanding of the problem we faced.
We will remove it from the git tree shortly.
