Not unless you are talking about a digital system with a PRI link.
If that is the case you could have that information aout of the CDR s’ or your billing system.
It may work also if you have a T1 non-pri with DTMF caller ID (not very common, only on the US).
On analog, you could still get the port number out of the CDR ‘s, but the caller ID needs to be “fished out ” by the billing system.
