[SIPForum-discussion] Conference

[Donald Lee]

Hi amit:

      You are totally right, the media mixing is the most important thing
during realize the
conference feature.
      There is two way:
      1. As you said, find a server that can support media mixing. But it's
too hard to find
a free or simple server. I think most of them are commercial. Such as
Huawei, Erricsson
or other suppliers' expensive equipment.
      2. The UE of your device can support media mixing. That's means your
device do all
the things individually. The server just route the messages and do nothing
else. Of cource
it depend on the DSP chip. But most of the comm DSP chips, such as TI,
Broadcom and
so on, support this feature all.

     In my opinion, I think the second method is better than the first. The
UE has the ability
to decide what will do and how do. I think it the principle of SIP.
