[Serusers] [PRESENCE]-Subscription does not exist

[Vaclav Kubart]

Hi,
this response means that subscription to the user 111 at xx.com and dialog
identifier Call-Id: ssc-3d959a71f819794a430784374ee6f664 at 4bfc7569f5fad1a1a28a85dcb86badbb,
To tag: a6a1c5f60faecf035a1ae5b6e96e979a-9321, and From tag: 3ffe8a226de90fb471c542cb1065d20a 
is not known by server. It could be destroyed before this SUBSCRIBE
arrived or whatever. If this is first SUBSCRIBE request sent by your
client - but I don't think so - it is invalid because has both tags.

You have to catch all messages related to such dialog and you can see
the reason for this behaviour from them.
