Look in your CUCM ig there is an IP in your gateway's page, if not, Its not registered, the registration status does not tell you the truth, the IP does.

If there is no IP address reset/restart the gateway in the CUCM.

There is IP For G.W in CUCM-Gateway Page

Can you please post the show run from GW? Its seems issue to be with TECLO where we are getting power denial event.

As call hitting the GW and matching incoming and outgoing dial-peer , when call traverse over the fXO port its power denial.

In order to test the FXO port or teclo issue, can you please connect analog phone to that port and make test call.

Hi Faziz,

Please provide some more details.

CUCM version, phone model being used, when do you get fast busy ( after going off hook or after the called party responds ? etc?

Which codec is being configured between ip phone and h323 gateway and also on CME dial-peers? if the two calls legs are using diff codecs then is there a  transcoder configured?

What is the DNA result shows?Is the call hitting the GW?

Can you please debug the GW atleast see whether call hitting the GW if not then we can troubleshoot on the first node.
