[SIP Beyond VoIP] Presence problems continuation

[Hadzhiev, Tihomir]

Hi Adrian,

I have checked around and it happened that 1-st problem is that when my ISP user logs in , the Subscribe for the XMPP domain is not routed correctly towards SYLK.

That's done now and I can see in tcpdump, e.g. done correctly ( even though it forward also the Subscribe for the SIP domain ( 1 user though ).

But now the following problem appeared:
