Caller ID in FXO port.

[rhegde]

Hi,

Can I have Caller ID in FXO ports ? I am getting conflicting information. Some docs say you can and some says you can not have caller ID on FXO ports.

Thanks

Ravi

Yes with H323 no with MGCP and CCM as Call agent

In MGCP mode, to/from IP phones, FXS and T1/E1 PRI (Caller ID currently not supported on

FXO and T1-CAS)

In H.323 mode, between IP phones, FXS, BRI and T1/E1 PRI; and from FXO to IP Phones, FXS,

BRI and T1/E1 PRI

I'm also under the impression that you can't have Caller ID with analog ground start FXO trunks. I've been told that they have to be loop start in order to get Caller ID.
