Is it the responsibility of the B2BUA establish call even if both the end pionts don't have compatible media codecs.

While connecting A & B, can B2B terminate one callleg (ie. A --- B2B) at B2B and start one more (ie. B2B-------B), also B2B will do the codec conversion for imcompatible codecs. In this senario there will be be 2 RTP sessions established for the single call. If so then which is the best place >> I dont think B2BUA will come in the RTP path, it will only control the >> session and the RTP woudl be between the orig and term ports described in >> the indivdiual SDP.. for the codec converter 1. Along with B2B 2.
