Call Forwarding Number

Hello All

In Call manager for a line i set-up call-forward settings to a gsm number.When i call from a gsm number to my ip phone,in my gsm number ( forwarded one ) i see a Call manager number DN.Call manager seems to make the call but i want to see the calling number.For ex i am calling 2063 ( redirected to 0 532 345 34 55 )  from a gsm phone ( 0 533 456 32 21 ).In my gsm phone screen i want to see tha calling one  ( 0 533 456 32 21 ) but i see a call manager number.How can i fix that ?

Thank you...

Call Forwarding Number

It's a routine request from CUCM users but I am affraid it is working as designed & there is no way to manipulate it with present CUCM versions. Perhaps CUCM 9.x might have a fix for it.

Above behavior is due to the fact that, CUCM initiates a new call leg in offnet-to-offnet call transfer/forward, hence the ANI will be of CUCM end point than the calling PSTN number. I know this is possible with other PBXes ( e.g. Avaya ) but the feature is yet to come to CUCM. I'd be glad to know if someone has achieved it with CUCM.

If it helps, pls rate.

Call Forwarding Number

Hi,

On the CUCM look at the Gateway set up page for the outgoing gatway to the GSM

OUTBOUND CALLS

Calling Party Selection --> set to Originator

Callining Party Presentation ----> set to Allowed

Worth a try.

Re: Call Forwarding Number

This is possible if you use Mobile Connect instead of CFA. CUCM will set the ANI (From) of the remote destination call leg to the original called number and the RDNIS (Diversion) to the enterprise DN. Be advised that your carrier must support/allow this; not all do.

Also, acampbell's idea is something I haven't noticed before. It's worth running a few debugs - such as 'debug isdn q931' on the gateway - to see whether CUCM attempted to use the original ANI or not. Again it's possible that the carrier blocked this value since you don't pay for that TN.

Re: Call Forwarding Number

Like others have pointed out this can be a Carrier Block or the Carrier is not using the " , By default CUCM sends out the Redirecting number in the ISDN MSG.

See debug here below from debug ISDN q931 of a Call which then forwards out to a Mobile.

Numbers involved calling number

5556666 Calling number

7778888 Called numer ( CUCM number which then forwards the number out ) 8888 ( is the CUCM Int Ext )

8889999 Forwarded number( Mobile Number ) ( this is the number which 8888 is CFWd to )

5556666 Shows up on The Mobile. Even though the call is coming from 7778888 Technically.

                Plan:Unknown, Type:Unknown

        Redirecting Number i = 0x00008F, '8888'

                Plan:Unknown, Type:Unknown

So take a look at your debug and see if its something like that, if the number still shows up at your end with the wrong number then your carrier is the issue.

Re: Call Forwarding Number

It can't be done
