Asterisk - audioredirect to external audio device possible?

Hi!

Is it possible to communicate with a device which is only able to send and receive rtp packets (no signaling - e.g. SIP)?

Example:
SIP Phone (ext. 1000) calls 2000 (configured within sip.conf), asterisk is forwarding all audio traffic from SIP Phone 1000 to this special audio device…

Kind regards
