Note:
If a new party joins a conference immediately, and the party is an H.323 IP trunk user, the caller cannot have a talk path with the other parties in the conference. To prevent this situation, include a short delay in the vector at a point before a new party joins the Meet-me Conference. This delay can be a step to collect digits, a 1-second delay, or an announcement. Since Meet-me vectors are almost always configured with announcements and digit collection, this situation is rarely an issue.
