I need to enter several thousand dialed numbers which will all be mapped to the same call type. Instead of adding each individual number or bulk imporing them can I use a wild card?
This cannot be done in ICM. Your only option would be on the Routing Client where the call originates. For example, in a UCCE environment you could create a wild card in Call Manager and send all calls hitting that wild card over to UCCE with the same shared DN. Of course, this is oversimplifying the necessary steps and doesn't take into consideration any reporting requirements.
