Transfer function

Hello!
Can I use the transfer application to transfer to another server? It currenly works only, if I transfer to an internal number or extension. If I specify in the destination URI a different server IP, it fails.

Transfer never operates locally. If there are restrictions on the destination, those are being imposed by the upstream user agent.

Thank you. It is OK now. If I answer, I see the REFER message. If I issue progress, I see MOVED message.
