Caller ID on gateway FXO ports not working...

    I've set up Cisco gateways with PRI's in the past and caller id always works
    flawlessly. However, I recently set up a 2811 with a 4 port FXO card. The
    telco has confirmed that they are sending caller id, but I am not getting it
    on my devices.

    When I go to the voice-port and set 'caller-id enable', all calls stop
    coming in from that port. Doing a debug, it looks like the port may be
    hanging while looking for caller id information. There does not seem to be
    an mgcp connection at all. Doing some research, it appears that there are
    different means of sending caller id and I need to be in sync with the

    Anyone out there have any experience troubleshooting this? Any tips?

  2. Hi Jim,

    Caller ID cannot be passed from a Foreign Exchange Office (FXO) port on
    any of the 1700 Series Access Router, 2600 Series Multiservice Platform
    and 3600 Series Multiservice Platform gateways that run in Media
    Gateway Control Protocol (MGCP) mode. However, the caller ID can be
    passed from a PRI or a Foreign Exchange Station (FXS).

    If caller ID support is essential on the FXO port, configure the
    gateway to run in H323 mode.

    Thanks for the response. However, I'm not sure we are talking about the
    same thing here. I may not have quite specified, but I'm talking about
    incoming caller id, not outgoing. I'm trying to get the caller id of the
    incoming call and pass it to the end device (7940). Any comments?

    Brad is right, CLID is not supported in MGCP mode for the FXO. If you
    really need CLID change it to h.323.


    [Snip: Table 2 Voice Gateway Router with Cisco CallManager Feature

    Caller ID support

    Enables the Voice Gateway Router to send the ANI of a caller for display:

    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

    Let us know if this solves your query..

    BTW this is still being true for the 2800 series and 3800 series, this
    is the right link for your platform, just look for the same table (but
    number 1 in this case) mentioned in my previous post.
