Snom RLS subscription fails in SipX 4.2.1
-----------------------------------------
Key: XX-8652
URL: http://track.sipfoundry.org/browse/XX-8652
Project: sipXecs
Issue Type: Bug
Components: sipXrls
Affects Versions: 4.2.0
Environment: Clean Install from ISO (4.2) updated to 4.2.1-018930
Reporter: Rene Pankratz
Attachments: subscribe_failed_4.2.1-018930.pcap,
subscribe_successful_4.0.4-017289.pcap
Snom Telephones are not able to subscribe RLS with SipX 4.2 anymore.
sipxrls sends "415 Unsupported Media Type or Content Encoding"
___________________________________________
I'm not sure how far the discussion has gotten on this issue, but the problem
stems from the fact hat 4.2 enforces the requirement for a resource-list
SUBSCRIBE to include "Accept: application/rlmi+xml", as the RLMI part of the
notification describes the resources in the list. See section 4.2 of RFC 4662:
4.3. NOTIFY Bodies
An implementation compliant to this specification MUST support the
multipart/related and application/rlmi+xml MIME types. These types
MUST be included in an Accept header sent in a SUBSCRIBE message, in
addition to any other types supported by the client (including any
types required by the event package being used).
In general, if a subscription has notifications of type multipart/related, the
MIME type of the "root component" of the notification must also be named in the
Accept of the SUBSCRIBE.
The solution is for Snom to add the above value to the Accept list in its
SUBSCRIBE.
