UA can send a CANCEL for the re-Invite, followed by re-Invite getting terminated by 487. Than the call should switch back to the case as if re-invite is never received. Re-invite needing a human interface or not is up to the local policy. some vendors give the access/some do not to the user.

Hi, does an in-dialog CANCEL for a re-INVITE make sense? Well, I understand that a re-INVITE never requires human input so it's automatically replied by the UAS/proxy, but what about if the UAC sends a CANCEL for a re-INVITE? Is is safe to ignore (this is: reply 200 and forget it) an in-dialog CANCEL? -- Iñaki Baz Castillo <[EMAIL PROTECTED]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
