How many SMDR connections can i have to the MCD
We have come accross some sites where they have a CCM and a Call logger and a Voice recorder which all connect on port 1752 to the SMDR
When you try an connect a second CCM the SMDR connections fails.
In default MCD version 5 (think its higher in version 7) is set to allow 3 connections
As it says below in the help file this can be changed to 10. Requires a reboot.
