Hi Stefan,
as usual the explanation is easier then on the first look ;-)
Expires: 0
means you want to de-register the Contact. Because the de-registration was successfull SER does not include any Contact in the response.

Hi,
registrar at iptel.org (0.10.99-iptelorg/tekelec-SOPv2) and ser 0.9.6 as well do not return a contact header in 200 response to REGISTER (see trace below), but in rfc (10.3) I read it's a MUST
8. The registrar returns a 200 (OK) response. The response MUST contain Contact header field values enumerating all current bindings. Each Contact value MUST feature an "expires" parameter indicating its expiration interval chosen by the registrar. The response SHOULD include a Date header field.Am I missing something (apart from the contact header) or is my register message not correct?
