Or Put another Way Asterisk acts in SIP terms as a Back2Back User Agent, to terminate one side of the call let and originate a new call leg with a different codec profile in the SIP/SDP. Asterisk then terminates the inbound media, transcodes it an originates a new media stream on a completely different call leg.

UA----->OpenSer(Outbound Proxy)---------Register Server |
|
| Asterisk(codec converion)----------------------The UA will register to Register server through outbound proxy OpenSer.
When
UA makes call it first comes to Openser, OpenSer should route the media
to
Register server through Asterisk for codec conversion. OpenSer will not
hold
any User account rather it will act as a proxy.
Asterisk cannot receive *just* the media, it needs to receive the SIP signalling so then it can handle the media (and do the codec conversion).
