<br>
<tt>You can use the local route to do routing on the outgoing requests - like doing drouting, or usrloc lookups. But in B2B mode, some signaling related functionalities, like dialog support, accounting support will not work (because you do not have a proxy
transaction, but only a UAC one) - of course, you can do manual ACC (directly from via script functions)..</tt><br>

<p class="MsoNormal">I have been reading through the documentation for the B2BUA functionality. I want to use a B2BUA while also having many of the proxy functionalities like drouting, accounting, etc. However, it is indicated that they do not work easily together.<o:p></o:p></p>

<p class="MsoNormal">The B2BUA Tutorial says this:<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:10.0pt">A solution is to consider that b2bua is a separate instance (logically speaking) which selects types/classes of destinations. A proxy instance will responsible for routing inside the class of destinations.</span><o:p></o:p></p>

<p class="MsoNormal">It is also noted in the tutorial that outgoing requests from the B2BUA module will trigger local_route processing. So my question is this:<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Can the proxy functions be performed in local_route, prior to sending out the message? Would any callbacks registered for the message in local_route take precedence over the B2B routing logic?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Or must the message be actually sent out, via loopback ideally, so that it can be received again and processed as a proxy?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Also, is there any plan to implement Binary Interface replication for the B2BUA module like it was done with Dialog and UsrLoc for faster failover?<o:p></o:p></p>
