[Kamailio-Users] Presence_Dialoginfo versioning

[kamailio.org at spam.lublink.net]

Hey,

I have noticed that the XML body of the dialog messages contains a 
version attribute. The server is counting the versions using the latest 
subscription as a reference point, and the phone is counting the 
versions from the first subscription ( at reboot ).

Which is the correct way to count these versions?

Consider :

10:00 Subscription
10:05 Notification version 1
10:35 Notification version 2
11:01 Subscription
11:05 Notification version X

Is X = 3 because it is the third notification or 1 because it is the 
first after the last subscription? If it's version 1, it could confuse 
the phone cause a notification that is sent at the same time as the 
notification would have a confusing version.

On the other hand, each subscription, has it's own versioning, so would 
it not logically follow that the different subscriptions for the same 
device have seperate versioning?

 From my phone : BLF Notify received for line: 3 has older version: 3 
last version:135

To confirm my theory, I redialed the number 133 times, and once the 
version number had run up to 136, the lights started flashing again.

Is this a bug in Grandstream, Kamailio, or perhaps an RFC which was unclear?

Thanks,

David
