User's call forwarding not working to their cell phone

[dittocisco]

I have a user setup where there CFA CSS is set to allow them to dial 9 plus their 10 digit local number.

This part works I guess (I'm new to CUCM and CSS stuff)...the user is able to hit CFwdALL and dial 9859907xxxx and it accepts it.

The  problem though is that when you call their DID at their office from an outside line all you  get is "we're sorry your call cannot be completed as this time".

I  "think" the calls are getting to the CUCM but are possibly not routing  out again correctly...possibly changing the outbound sending # to the  original caller instead of the user's DID, causing the PSTN to drop the  call since it isn't coming from a valid DID on that PRI/link/network.

Anyone  know how to troubleshoot this or solve this?  All I want to do is allow him to forward his calls to his cell phone.

You'll need to debug the GW you're using to find out what's the calling number you're sending

As a "level 1" check you can use the dialled number analyser.

Serviceiability page-> dialled number analyser -> Analysier -> Analyse.

this will let you know if your CSS and PAT is set right for a specifc number and will also let  you know were the call is going to as per the current route plan.

Have a look and see if the param block offset to offset transfer is false in service params Cisco calls manager advanced.

Else attach a set of detailed traces with enable gatewAy trace along with call info.

The block offnet to offnet transfer is set to false.

I will gather a set of traces on the gateway and post back.

Turns out after working with TAC that the CSS for the CFA was incorrect, causing it to hit a Calling Search Space that changed the outbound caller ID.

Fixing the CSS caused it to work ok.
