Help needed with call forward

Hello,

When I use *52 for call forward when no answer it does not work.
If I answer the call on my SIP extension, I can use “transfer” to send the call to my mobile.

But when I dont answer after 30seconds it does attempt to send the call to my mobile, but there is no Audio stream between the parties.
No matter which carrier I use.

This is the debug I think relates to it, it starts from when the call is diverted to the mobile.
