Can I forward multiple callers call to another number? Will they all go through?

For example:
Let’s say I give 100 people a local number in Paris and invite them to call for a conference call.

I do however forward all the calls made to this local number to a number in the US that hosts such conference calls.

Will all the 100 callers be forwarded to the US number? Or can Skype can only handle one call at a time?

Thanks
