Cisco Cube outgoing calls only display the sip-ua number

Hi all,

 

just configure a cisco cube. Incoming and outgoing calls working fine till now.

Just facing an issue by outgoing calls. Any call will display the sip-ua registered number.

 

Is there any possibility to send the invite with the calling extension number to the provider ?

 I think, generally any outgoing calls on SIP trunk don't carry individual caller-id.

 Also ISDN PRI signalling normaly carry callng party details but don't think SIP do the same by default.

 

 See below details I read in cvoice book;

"

Blocking and Substituting Caller ID

The caller ID information is private information. In ISDN, there is a private setting that can be set to protect this information. However, when SIP gets the caller ID information,

it does not hide the private information. Rather, it just sets a field to reflect that it is private and not to display it on a caller ID display.

The block option allows the gateway to delete the caller ID information from the SIP message requests so that it cannot be read on the network.

The substitution option is helpful if there is no Display Name field but there is a number and the presentation is not prohibited. In that case it copies the number into the Display

Name field, so that the number is displayed on the caller ID display of the recipient. The Cisco gateway omits the Display Name field if no display information is received".

 I hope it helps.
