Thank you very much, Mike, for your fix!

It looks like it helps. I do more tests tomorow (I am at CET).

Presence message is as follows:

PUBLISH sip:0002*25 at ip6.server.tld SIP/2.0
Call-ID: b005315c3d071250ecf07fffa5fff66e at
From: <sip:0002*25 at ip6.server.tld>;tag=72e3e8d1
To: <sip:0002*25 at ip6.server.tld>
Via: SIP/2.0/UDP

Content-Type: application/pidf+xml
Expires: 300
Event: presence
User-Agent: SIP Communicator 1.0-alpha3-nightly.build.1519 Windows XP
Content-Length: 423

<?xml version="1.0" encoding="UTF-8" standalone="no"?><presence
entity="sip:0002*25 at ip6.server.tld"><dm:person
id="t1998"><status><basic>open</basic></status><contact>sip:0002*25 at ip6.server.tld</contact><note>Online</note></tuple></presence>

And on pcap dump I see ICMPv6 response unreachable (Port unreachable),
but FreeSWITCH works ok and process calls on both IPv4 and even IPv6.

Thanks once more!

Beste regards,
