Note The PBXs should be configured to pass all DTMF signals to the gateway.
Cisco recommends that you do not configure “store-and-forward” tone.
If you change the gain or the telephony port, make sure that the telephony port
still accepts DTMF signals.
Note After completing E&M configuration, configure the route pattern and dial plan
and save your configuration, as described in the “H.323 Gateway
Configuration” section on page 5-16.
At this point in the configuration process, make sure that Cisco CallManager is
properly configured to provision the Catalyst 4224 and to configure MGCP
endpoints or H.323 route patterns, as required. Refer to the Cisco CallManager
Administration Guide or to the online help for the application.
Refer to the Cisco IOS configuration guides and command references for details
about specific VoIP commands and options.
