Call forwarding, no audio, help

Asterisk Asterisk SIP
1

Hello,

when I forward a call I have no audio (2-way).

The problem seams to be the same as:

but I can’t find a network problem.

When I answer the call before (using emty announcement), the forwarding to mobile device works.

That can be a perfect fix, but I don’t want to answer the call before the forwarding destination answer the call.

All ports SIP ports are open and not restricted.

Please help!

Thanks.
