IOS H323 Gateway Configuration to POTS (PSTN)

    I have the following Config

    Cisco CallManager 4.1(3)sr3
    Cisco Unity 4.2.1
    Cisco 2811 Voice Bundle w/VIC2-4FXO running 12.4(6)T Advanced IP

    The 4 FXO ports on the 2811 are connected directly to the PSTN

    My issue is as follows:

    Everything works very well with MGCP, but we have a requirement now for
    inbound Caller-ID on these FXO ports and need to move to H.323 as I
    understand it to make caller-id work.

    I have toyed with most of the sample configs on CCO to no avail.

    Does anyone have a working config for an IOS/H323 gateway over FXO

    Thanks in advance for the assistance and have a great day!

    IOS H323 Gateway on POTS CCM 4.1.3 using FXO

    Were you able to find a solution to this? I'm working on a very similar problem. I can make calls outbound using the FXO port but can't recieve a call in from POTS to an IP phone on CCM???
