I was trying to make sense of the log. I did find out that 6012 is an extension, but it's part of a voicemail retreive group. The 91XXX.. is the phone number that was dialed. But I'm not sure what AT023T is after the number. Seems like T023 is a trunk number, but what do the other letters represent?
After more work, it looks like a call came in at 10:25 and got transferred to ext. 6012, but it's not a actually voice extension. Then at 10:26 a call went out to 91xxxx... So I'm trying to find out if someone is calling from the outside to use our line to call out. Thanks.
