What is mscFrUniIsdnLastUsedCgpn?

This object holds the ISDN calling party number that most recently used this B-Channel; it shows a null string once the channel becomes free. An admin reviews this digit string when troubleshooting call setup issues, to see which remote number's SVC call last occupied a given B-Channel. For example, this might return a digit string like '18005551234' identifying the last caller, or an empty string if the channel is currently idle.
