## Comments

- **VirtualServiceDetail.channelType**: As this type defines what the virtual service is, it then defines what address and additional information might be relevant.

Some profiles could be used for specific types to define what the other values could/should be.
- **VirtualServiceDetail.maxParticipants**: Some services have only a limitted number of participants permitted to connect at a time, this is typically used in "shared" virtual services that you might find on location resources.

Typically on-demand services might not have these restrictions.
- **VirtualServiceDetail.sessionKey**: Some services require a session key to be able to access the service once connected.

This could be in cases where a shared number is used, and a session key is added to put into a private line, or to identify the participant in a call.
