There's a few things to be aware of, though:

  - H.323 to SIP doesn't pass on out-of-band DTMF correctly
  - in a Tcl app, you can't use an inbound voip leg in a leg setup
    that creates an outbound voip leg (you'll get an ls_009). You
    can create the outbound voip leg without an inbound leg, then
    manually do a "connection create" to join the legs, but in that
    case, the outbound leg will have a different GUID/h323-conf-id
    than the inbound leg - most annoying.
