may I correct?

Example - IPv6 OK message.

Via:SIP/2.0/UDP [AAAA:BBBB:CCCC:DDDD:EEEE:FFFF:GGGG:HHHH]:5060

have done corrections to VIA header as above, also applies other places in
the SIP message where host part used is an IPv6 address.

Ljilja,
        SIP doesn't really care - the fields that will contain addressing
information - if containing dotted decimal and not FQDN are large enough to
support IPv6 format. eg the Domain part of  the From, To and Contact
fields.... You should concern yourself with Firewall's and IPv4 to IPv6
gateways (Dual stack transition methods)etc.

Example - IPv4 SIP OK message.

SIP/2.0 200 OK
Via:SIP/2.0/UDP 192.168.100.203:5060
From:<sip:[EMAIL PROTECTED]>
To:<sip:[EMAIL PROTECTED]>
Call-ID:[EMAIL PROTECTED]
CSeq:102 REGISTER
Contact:<sip:[EMAIL PROTECTED]:5060>;q=0.5;expires=3599
Content-Length:0

Example - IPv6 OK message.

SIP/2.0 200 OK
Via:SIP/2.0/UDP AAAA.BBBB.CCCC.DDDD.EEEE.FFFF.GGGG.HHHH:5060
From:<sip:[EMAIL PROTECTED]>
To:<sip:[EMAIL PROTECTED]>
Call-ID:[EMAIL PROTECTED]

CSeq:102 REGISTER
Contact:<sip:[EMAIL PROTECTED]:5060>;q=0.5;expires=3599

In regard to the IP, could you please outline the major
requirements for upgrade from v4 to v6 - SIP related exclusively.

Thanks a lot,
