[Serusers] Contact in 200 OK response to REGISTER

[Stefan Sayer]

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?

Stefan
