Outbound Caller ID is showing Unknown Number

We have a problem where when we call from our desk phones (CUCM) to 3G wireless phones, the wireless phone will receive caller ID as “unknown number”. We contacted our telco/PRI provider to check the digit that we are sending and it was ok.

Then we contacted AT&T and made some tests and found out that the “unknown number” is only happening to 3G wireless user and it is only for local number (7-digit dialing)

AT&T said that “The Calling Party Number parameter as it is sent in from the office number is not set according to standards. The Numbering Plan is Unknown and should be ISDN/Telephony. In addition, the Screening Indicator is Reserved - User Provided,Not Screened and  it should be Network Provided or "User-Provided - Screened and Passed”

Questions:

Is this some configuration in our system or with telco/PRI provider?

Thanks,

sienz

Re: Outbound Caller ID is showing Unknown Number

You can set that under your PRI/H323 config and also using calling/called party transformation patterns.

Telcos can also override and change it, but you need to start by sending it correctly from CUCM

H323
Call Routing Information - Outbound Calls

MGCP
Call Routing Information - Outbound Calls


On left hand from above there is CALLING party transformations if you need them as well.

Re: Outbound Caller ID is showing Unknown Number

Its a telco issue show this to them

        Calling Party Number i =  0x0081, '7028582580'

                Plan:Unknown,  Type:Unknown

        Called  Party Number i = 0x80, '2688622'

                Plan:Unknown, Type:Unknown

if we send the calling party number no amount of config will fix this issue since we already send the calling number

Re: Outbound Caller ID is showing Unknown Number

It's entirely possible that even sending calling party number the provider doesn't accept it if you are not sending the type. Please confirm from your provdier what type they would like to see.

Re: Outbound Caller ID is showing Unknown Number

Thanks all for the input, especially Javalenc.

The Calling party Number that we are sending is correct according to our telco provider but AT&T (as the receiver) said that Screening Indicator and the Numbering Plan is not acceptable to their 3G network. AT&T also confirm that they receive a good phone number but the Screening Indicator and the Numbering Plan is not acceptable.

I will try changing it on Monday based on Javalence Document.

Re: Outbound Caller ID is showing Unknown Number

They may insist that you set plan/type to their spec, but the Screening Indicator is already correctly set to "user-provided, verified and passed". Note also the Presentation Indicator is correctly set.

Re: Outbound Caller ID is showing Unknown Number

Thank you for checking it and for the link p.bevilacqua.
I will verify it again on Monday.

I guess, it may come down to "The Numbering Plan is Unknown and should be ISDN/Telephony"

Also if the screening indicator is already correctly set, the telco may override it so I will need to check to our telco provider what they are sending.

Thanks again

Re: Outbound Caller ID is showing Unknown Number

You will see that is easily solved.

What I do in similar cases, is to fix it from home during the weekend, then show up late at the office on Monday explaining how the issues took most of the day talking to telcos.

Re: Outbound Caller ID is showing Unknown Number

We found the issue,  It is in the gateway.  Someone put this on interface Serial0/0/0:23, it is fixed after it is removed

isdn map address . plan unknown type unknown.

Thanks all
