CM external call forwarding CLID

Maybe but it might not be easy.
If I understand right, you want external caller A to call station B forward to C and you would like C to see the number of B instead of A?
What's the use case for that? Is B like an on-call number that you're forwarding to someone on call (C) and you'd rather C know that the on-call number is ringing instead of them knowing which person (A) called it?
You could probably do something with VDNs and VDN override to pass the VDN number (which would be B in the example) to C if you set the call flow up right.

You are right.
Our service provider restricted external call forwarding to external number. I have to override this restriction.
Internal DID station caller A to call station B forward to external number C and I would like C to see the number of A instead of B. It is working well.
But external caller A to call station B forward to external number C and I would like C to see the number of B instead of A because our service provider restricted caller A to call external number C. Only way to override this restriction external caller A to call station B forward to external number C and I would like C to see the number of B instead of A.
Thanks
I'd say fight with your service provider...I've heard of them restricting what numbers you can present on redirected calls, but never that they outright reject them.
Is it because they use the same parameter like PAI for both CPN and authentication of the caller - so if CPN is not a number that lives on your SIP trunk, they reject the call?

I've seen that in weird SIP implementations - why can't you just have your service provider replace with BTN and let the call pass? What country are you in? Because that's not a restriction I'm familiar with where they actually reject the call.
There are a few special applications in CM that might help - SA9025 and SA9086.
But here's a good post that might help:
