Actually we did send INVITE to UA specifying both G729A and G729B. UA
did not reject the Call. We configure the UA's codec to G729A and G729B
separately and they worked.
 However, some UA may not like it.

  Here is a sample SDP that specify G729A and G729B.
  
  v=0
  o=root 743184990 743184990 IN IP4 10.50.10.146
  s=call
  c=IN IP4 10.50.10.146
  t=0 0
  m=audio 10014 RTP/AVP 18 18 101
  a=fmtp:18 annexb=no
  a=fmtp:18 annexb=yes
  a=rtpmap:101 telephone-event/8000
  a=fmtp:101 0-15
  a=ptime:20
  a=sendrecv


  I think G729B is G729A + VAD.

  Correct me if I am wrong.

I do not think it is possible to indicate support for G729A & G729B in
same offer. G729B and G729AB are fully interoperable.
