Subject: Re: [h323plus] Transfer call
With the original definition, I don't think there is a way to know
beforehand. You can try it and see if you get a response back.
>From what I understand H.450.12 is supposed to solve this, but I haven't
seen it in action anywhere, yet.
The Mirial softphone supports H.450.2 and I've seen a few IP hardphones that
do, but H.450 in general is not very widely implemented.
Its a shame that not even those expensive videoconferencing units can do a
proper call transfer like any $10 traditional phone can...
