Caller ID passthrough from analogue lines

[mrchips]

Hi, a newbie here.

We've 3x analogue voice lines hooked up to a ShoreGear 50 switch running Mitel.
Caller ID isn't getting passed through from the analogue lines.

Our Mitel support team are telling me that it's not possible to have CID passed through from an incoming call on an analogue line. Therefore if I miss a call on Mitel Connect and it diverts to my cellphone it will only ever be able to show the incoming CID as the main company analogue trunk number.

They're telling me the only way to get CID passing through correctly is to upgrade the voice trunks to PRI/SIPs.

Is this correct? Or is it they just can't be bothered to try and make it work?

Mitel is correct. Caller ID on analogue lines require a special "modem-like" signal sent between rings to detect the data. Mitel analogue lines *might* have the capability to *send* such data but it wouldn't have the capability to receive it.
