<tt>In this case, I guess that the OPenSIPS B2B (handling
the REFER) should sit between the OpenSIPS LB and Asterisk
- again , this is the case only if the result of the
transfer is a call to an Asterisk box too. If the call may
be redirected back to a carrier, the OpenSIPS B2B should
sit in front of the LB.</tt><br>
