Identify TN from which a call arrives?

[minermail]

We have many Opt11s that have local analog telco trunks plus digital connectivity. Our telco billing is just now being centralized. I'm looking for a way to identify via calling which trunk TN an inbound call hits the Opt11 without having to dispatch someone for a physical check. The goal is simply to audit the telco services to make sure everything being billed is actualy in use at the site (excluding obvious non-PBX connected services for security, modems, SEB, etc..). Ideas or suggestions would be appreciated.

almost impossible.. i have found trunks that were software outed decades ago and still being billed. unless you dial each pots line and get an answer.. then you may have groups that are outbound local and you never get an answer or a ld bill on... ld 36 can give you a list of cot's that have not been used the longest.. but that only works for cot;s not did's or ties or wats...

i would suggest a site visit if these sites are older you have numbers that need to be off the bill..

A site visit would be the best way, you could try to remote into the PBX and stat your trunk cards when calling each number to see what TN goes busy. The only problem with this way, is there is no way to tell which call is yours, if other people are calling in at the same time.

Couldn't you dial into the option 11, then on a seperate phone dial a known number and trace it in LD 80? Wouldn't that show how the call came in without having to visit it on site?
