Use H.245 tunnelling.

Also, H.323v4 will explain how to do TCS and M/S at the same time as fastStart during call setup so that they be completed extremely rapidly. See 8.2.3 of the H.323v4 draft.

If you need H.323v2 or v3, you can still use H.245 tunnelling, and initiate TCS and M/S from the called end as soon as possible (right after sending fastStart)
