  • Caller ID Question

    I need to verify something here. Lets say that site A (Oklahoma City) has PRI trunks, and site B (Atlanta) has analog loop start trunks. A user in site A calls a customer who is local to site B. The call will go out over Site B's analog loop start trunks. Here's the issue......the caller id that the customer receives is the caller id of site B.

    If you reverse this situation and someone at site B calls a customer who's local to site A, the call is place out over site A's PRI trunks. The caller id that the customer receives is the caller id of site B.

    So my question there a way for the caller id of site A to pass through the analog loop start trunks of site B? Or is this just a difference in architecture of the trunks that can't be changed? Iím getting complaints that some people arenít answering their phones because they think someone from site B is calling them when itís really someone from site A.

    Analog trunks do not support sending outbound caller ID. PRIs do.

      They don't support outbound caller id, or they don't support caller id pass through?

        Both. There is no mechanism to send it. To change it, you would need to contact the telco.

          Check with the LEC. I was on the phone with AT&T support recently and they mentioned something that I had not heard before about passing CID out... I didn't pursue the mentioned item because it was not relevant to my conversation with them... and I could have mis-understood.

          A workaround may be getting SIP Trunks... We have 8 in our office... 4 from EtherSpeak and 4 from Bandwidth. These have many features and they pass the CID from the user. We have developed a CID Changer so each user could use a "local" outbound CID.
