A,


Could you provide more information on the symptoms observed when the call fails? Also, on your voice gateway can you do the following:


debug isdn q931

Place a call to a toll free number and then post the output here.  If you do not see output on the voice gateway,


If you are using Cisco Unified Communications Manager (CUCM) then you may also want to load the DNA tool. Whether you have access to this tool will be determined by the version of CUCM you have. You could try: https://


I am assuming that you have confirmed local, long distance, and international (if applicable) calls are functioning as normal.


HTH.

Hi Ateeq,


I saw from the DNA output that you are using H.323 gateway.

What type of ports(T1,E1,FXO) are you using to connect to your Telco?

What dial-peer are you using on your H.323 gateway to route this toll-free number?


Regards

Nitesh

Hi Ateeq,


I just wanted some clarifications from your end for a better insight into this problem.


1) Which signalling protocol(MGCP,H.323) are you using between your gateway and CUCM?


2) What type of line(FXO,T1,E1etc.) connects your gateway to the PSTN?


3) Which version of CUCM are you using?


This may sound silly but i hope the route patterns for calling the tollfree number has been configured correctly on the CUCM and i am assuming that those patterns are ultimately pointing to the gateway through which you want the call to be sent out to the PSTN.(Assuming you are using an appliance model of CUCM,you can do a DNA and check whether the call is being routed to the correct gateway).


Check the section "Simple Analysis by using the Analyzer Window" in this doc for help on DNA

Hi Ateeq,


In the DNA analysis you posted all seem fine on the Call manager side. But interstingly I noticed that the "Calling party number" you are sending is 12100,  is your Telco(PSTN) expecting a 5 digit number as the calling party number???


Easisest way to check this woul be to do a DNA for a working call and then compare the  "Calling party number" from that!!!.



Also if you could tell what you where using to connect to the Telco, I could then tell you what debus to run on the Gateway so that we could go ahead and troubleshoot that


HTH

Dear All,


Thanks a ton for yours valuable & quick reply,


While debuging i found that cucm is not routing call to correct route pattern, it was routing to one of local 8 digit router pattern. i dont know why and i could not found any solution.

i feel this would be weird thigs, I deleted the local 8 digit route pattern and recreated, hurrrrreeeee found toll free call are working fine.


One again thank you soo much to all for help.
