<tt>Hello Jorge,<br>
<br>
I see your problem - the 2 BYEs have different Cseq numbers. Where
do you trigger the terminate_call function ? in what context and
from where exactly ?<br>
<br>
Best regards,<br>

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