Codec negotiation is end to end through normal SIP INVITE/reINVITE mechanisms. SipXbridge does not get involved in that choice. We did have codec filtering at one point but decided to remove that as there were interoperability problems with fax ( which needs to switch codec from G711 to T38 mid call ).
