For Interworking scenario IPv6-IPv4 we need information, concerning the general behaviour of IPv4 only SIP terminals.

Imagine an INVITE with a SDP, pointing to an IPv6 remote address for media

- Is it correct, that an IPv4 only SIP terminal would reject the call with 400 (client error: bad request) and warn-code 300 (incompatible network protocol)?

- What other situation could lead to this response?

Thank you for your assistence.

Best Regards,
Christian Schmidt
