When I call inside... FXO-M1 card get Caller ID number ... but I still have message: "From Unknown CallerID"...

Is it OK? Or I have some other options?

Thanks in advance.

Re: FXO-M1 - "From Unknown CallerID"

Are you using H.323 or MGCP to connect to call manager. Even if you have fxo-m1 callerid still does not work with MGCP. If you are using H.323 it should work but might not come on the first ring. Also make sure you have callerid enable under the voice port.

Let me know if this helps,

Thank you,
