Aha!
That's because hcontact->uri is not a pjsip_sip_uri, but rather it's
a pjsip_name_addr!
To get the pjsip_sip_uri, you need to do this:
uri = (pjsip_sip_uri*) pjsip_uri_get_uri(hcontact->uri);
which more or less means "get me the URI inside the name-addr, or if
you are not a name-addr, then return yourself".
