DNS isn't my *thing*, but IIUC, couldn't "whatever.invalid" be resolved to an FQDN of "whatever.invalid.example.com" if the node doing the resolving has "example.com" as its domain? To be sure, wouldn't it be necessary to specify "whatever.invalid." ??? Thanks, Paul On 2/16/201

Adding to what brett said... Why is it necessary to have a separate null address for IPv6? Null is null. Won't an IPv4 null address do? Even if your node doesn't support IPv4, I would think it could support a *null* IPv4. Thanks, Paul On 2/7/2011 7:09 AM, Brett Tate wrote: >> Wh

Hi All, Please clarify how to handle NULL IPv6 address in SDP c= line. According to the following snippet of RFC 3264 "RFC 2543 [10] specified that placing a user on hold was accomplished by setting the connection address to 0.0.0.0. Its usage for putting a call on hold is
