Description (partial)

Phone1 (SCCP) calls Phone2 (SCCP) over the dual stack SIP Trunk. 
Phone 1 then transfers the call to H323 fxs phone which is across 
the same dual stack SIP Trunk. There is no audio in the call and when Phone 1 does hold/resume the call drops.

This issue happens only when the SIP Trunk is IPv6 enabled. Doesn't occur if the sip trunk is v4 only.
