    I have 2 cisco routers, one with a dual-fxs card, the other with a dual-fxo card.

    I can successfully call from the PBX to the cisco with the fxo (main router) and then call to the fxs points.

    But in the reverse order, if i try to call from the fxs router(remote router) to the fxo router, it calls, the fxo answers, i dial a pbx extension and it rings… the extension answers, and i can hear the voice (from the pbx to the fxs), but they can’t hear anything (the voice from the fxs to the pbx)

    My configuration in the main router:

    voice-port 0/0/0
    cptone MX
    !
    voice-port 0/0/1
    !
    !
    mgcp profile default
    !
    dial-peer cor custom
    !
    !
    !
    dial-peer voice 1 pots
    destination-pattern 100
    port 0/0/0
    !
    dial-peer voice 2 voip
    incoming called-number .
    destination-pattern 20.
    session target ipv4:192.168.0.99
    dtmf-relay h245-signal

    My configuration in the remote:

    call rsvp-sync
    !
    voice-port 1/0/0
    cptone MX
    !
    voice-port 1/0/1
    !
    !
    mgcp profile default
    !
    dial-peer cor custom
    !
    !
    !
    dial-peer voice 1 pots
    destination-pattern 200
    port 1/0/1
    !
    dial-peer voice 2 voip
    incoming called-number .
    destination-pattern 10.
    session target ipv4:192.168.0.100

    (i just can’t understand , maybe it’s a silly thing i can’t see)

    Thanks in advance for any guidance.

    Your issue is the nat do you have firewal or a router between the voip

    I am facing only this issue with the nat

    Check for following:

    1. Ensure that your router does not have the no ip routing global configuration command.

    2. Issue the voice rtp send-recv in global configuration command

    3. Issue debug cch323 rtp command and the debug voip rtp command to identify the root cause.

    Need more help, send email at ciscovoipresource@gmail.com
