Customer has an Aspire M with PRI trunking. Due to business conditions they have subleased some space to a tenant and assigned them a block of numbers in our DID range. However, when tenant calls out, the party they call receives the CID info of the main business, not the DID of the tenant as desired. This results in customer confusion as they don't recognize the CID and often won't answer. If they do answer, they then associate the CID info with the tenant and are surprised when they call back and get the main business.

I know the Aspire should be able to pass the desired CID info via Q.931 signaling on the PRI but my attempts to set it up either fail to change the CID presented or cause the outbound call setup to fail. Any suggestions on things to check on the Aspire?

Do I need something like FGD on the far end of the PRI to make this work? Is there any way to view the Q.931 signaling exchange between the Aspire and the CO without something like the old T-BERD 224?
