IPv6 Problem
I have an IPv6 problem on my T46S.

Firmware is: 66.84.0.35

I have multiple lines configured and when using the IPv6 test line I have set up, though it works as I have both IPv4 and 6, the SDP and VIA in an outgoing INVITE has the IPv4 info.

The INVITE correctly goes to the IPv6 address:

INVITE sip:*9664@ipv6test.XXXXXX.com:5060 SIP/2.0
Via: SIP/2.0/TCP 192.168.1.160:12354;branch=z9hG4bK3608249627
From: "Daz" <sip:200@ipv6test.XXXXXX.com:5060>;tag=1006942405
To: <sip:*9664@ipv6test.XXXXXX.com:5060>
Call-ID: 4_72348378
CSeq: 1 INVITE
Contact: <sip:200@192.168.1.160:12354;transport=TCP>
Content-Type: application/sdp
Allow: INVITE, INFO, PRACK, ACK, BYE, CANCEL, OPTIONS, NOTIFY, REGISTER, SUBSCRIBE, REFER, PUBLISH, UPDATE, MESSAGE
Max-Forwards: 70
User-Agent: Yealink SIP-T46S 66.84.0.35
Allow-Events: talk,hold,conference,refer,check-sync
Supported: replaces
Content-Length: 308

v=0
o=- 20005 20005 IN IP4 192.168.1.160
s=SDP data
c=IN IP4 192.168.1.160
t=0 0
m=audio 11942 RTP/AVP 9 0 8 18 101
a=rtpmap:9 G722/8000
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:18 G729/8000
a=fmtp:18 annexb=no
a=ptime:20
a=sendrecv
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15

Hopefully, there is an easy fix?

Thanks,
Daz
