Paul,

Are you sure? A thread some time ago (http://lists.cs.columbia.edu/pipermail/sip-implementors/2002-November/004066.html) says they're not, quoting issues with shared dialog usages

Perhaps the interpretation should be that there is a contact per dialog usage?

Hi All,
    In RFC 3261,it is clearly mentioned that " For dialogs that have been
established with an   INVITE, the only target refresh request defined is
re-INVITE ".Similarly,for SUBSCRIBE created dialogs,What will be the the
Target refresh Request?

(re)SUBSCRIBE and NOTIFY are target refresh requests.

Paul

Thanks,
Suganthi
