Outbound Caller ID is showing Unknown Number

[sienz]

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

You can change the numbering plan to ISDN from unknown in the gateway configuration page under your PRI. See if that makes a difference.

You have number of places to play around with the Calling party numbers. If you have CUCM 7 or above you have much more options.

Check the Calling Party Transformation section in RP. That will probably the best place to start testing.

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

isdn map address . plan unknown type unknown.

Thanks all
