Are you sure, this 487 is generated by OpenSER? So far, i was not able to
verify this. Normally, this is reply generated by the CPE.
Some devices have a bug, which causes them to break the RFC (e.g. chinese
Gaoke devices): They use the Via-Headers from the CANCEL rather than from
the original INVITE. With the RFC-compliant handling of CANCELs since
OpenSER 1.3 this must fail, since the CANCEL is handled locally by the
stateful Proxy rather than just relayed to the original destination.
In OpenSER 1.2 the CANCEL was relayed to the original destination, thus
having all the Via-Headers the original INVITE had.

Hi Stefano,

can you give more details? I assume the 487 is generated from OpenSER? Any
error messages in the logs?
