Hi Jorge,

First of all, why do you want to use b2b support if you only need topo
hiding and to terminate a call ? For these you can simply use the dialog
module, which is a much lighter approach (with less probability for
complications).

Have you consider to use the dialog module, with topology_hiding()
script function and dlg_end_dlg MI function ?
