[Devel] multiple presentity entries

[Anca-Maria Vamanu]

Hello,

In RFC 3903:

  3. The ESC examines the SIP-If-Match header field of the PUBLISH
      request for the presence of a request precondition.

      *  If the request does not contain a SIP-If-Match header field,
         the ESC MUST generate and store a locally unique entity-tag for
         identifying the publication.  This entity-tag is associated
         with the event-state carried in the body of the PUBLISH
         request.


So generating a new entity-tag should be done for each initial Publish 
no matter if a record with the same attributes exist.
The idea is that there can be more publications for the same resource, 
useful in the case in which you have more devices registered with the 
same uri.

regards,

Anca
