Create phone conference using UCMA

Question

I'm trying to create phone-conference with UCMA 5.0.

This code works fine

info.Mcus.Add(new ConferenceMcuInformation(McuType.AudioVideo));
info.Mcus.Add(new ConferenceMcuInformation(McuType.InstantMessaging));
info.Mcus.Add(new ConferenceMcuInformation(McuType.Meeting));
info.Mcus.Add(new ConferenceMcuInformation(McuType.ApplicationSharing));

But if I adding this MCU

info.Mcus.Add(new ConferenceMcuInformation(McuType.Phone));

I got an error

The request failed with reason: mcuTypeNotAvailable

I need this MCU for external phone participants.

What is the reason for this exception?
