Summary: NOTIFY body absent 

Initial Comment:
Good afternoon! I have noticed something slightly odd about the presence module's handling of initial NOTIFY messages. 

Assume that user A has a subscription to user B. User B is offline. 

User A signs in. The initial notification message to user A regarding the status of user B does not have a body. This causes a problem in the Pidgin IM client. This client specifically relies on a valid body in the NOTIFY message before sending a 200OK response to OpenSER. If OpenSER does not receive that 200OK response, it cancels the subscription. Therefore, when user B signs on later, user A is not appropriately notified.

I have modified the Pidgin client to account for this misunderstanding. However, the Pidgin developers will not accept that change until the problem is rectified in the OpenSER code. It is their belief that the spec requires a body to ALL notification messages, no matter if the user is available or not. 

To see their comments, you can view the Pidgin ticket at this location:

Please feel free to contact me at Will.Hawkins at itt.com to discuss this matter further. Thanks for your help!
