Can you confirm exact call flow, so that I can suggest where we can prefix digits.

Below is the details i am sending to service provider, Service provider is telling is seeing calling party number as 265. So i want to prefix a 9 to redirecting number here. 

I created one test partition and CSS. Created new calling party transformation with this partition to add a 9 to calling party and applied it as redirecting party css but no luck.

        Calling Party Number i = 0x0081, '9193'

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '0732711456'

                Plan:Unknown, Type:Unknown

        Redirecting Number i = 0x000082, '265'

                Plan:Unknown, Type:Unknown

Hi Mohammed,

Sorry the settings is now working. Forgot to uncheck Use Device Pool Redirecting Party Transformation CSS before. Thanks for your response.

I have one more doubt here, i am sending the below details to SP. Service provider should see 9193 as calling number right? Not sure why he is seeing redirecting number as calling party number.

On gateway i have selected calling party selection as originator.

        Calling Party Number i = 0x0081, '9193'

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '0732711456'

                Plan:Unknown, Type:Unknown

        Redirecting Number i = 0x000082, '265'

I suspected the same thing :-)

Seems like SP issue.Calling party number should be 9193

Is this below statement from SP makes any sense guys. I have informed SP there is no such options in CUCM, caller ID should be placed based on calling party number

Our engineers have check the logs after the tests we’ve made yesterday and the answer is the same: your CUCM does not make really a redirect by anouncing before this our network with the help of specific message “facility”.

When a redirect call is made this message “facility” must be sent from CUCM to our network, telling us this call will be redirected.

Why they need separate facility message, when gateway/cucm is concatenating Redirection info in ISDN Setup.

Based on what you are sending the calling number is 9193. If the SP isn't seeing this then they have a problem.
