I invite you to an important session on Voice over IP

[Nancy-M Greene]

I would not say that SGCP and IPDC are at all replacing H.323. These
protocols are used between a Media Gateway Controller  (MC) and a Media
Gateway (MG), as device control protocols. An MG is used for telephony to
packet conversion, from, for example, PSTN to IP. Interworking with H.323
would occur in the MC and/or the MG.

>From what I understand, there is a new work item for developing a device
control protocol within SG16. I hope that SGCP and IPDC, and the imminent
merging of the two, will be considered as a basis for this protocol. There
will be a device control WG set up shortly in the IETF, as well as a mailing
list for this subject. I will forward this and the proposed charter for the
WG to this mailing list as soon as I receive it.
