Hello Freeswitch-users, In Freeswitch dialplan, you can route-hunt by stacking bridge commands like so: <extension name="internal"> <condition field="destination_number" expression="^1111"> <action application="set" data="hangup_after_bridge=true"/> <action application="bridge" data="sofia/local_profile/1111@@" /> <action application="bridge" data="sofia/local_profile/1111@example2.company.com" /> </condition> </extension> My question is - is it possible to have more fine grain control about when to route-advance? For example, it might be OK to route advance when example1.company.com is not reachable or returns a 5XX response code or doesn't return a 183 Session progress or 200, but it may not be OK to route advance on a 4XX for instance... Any ideas on how to have finer control? I haven't found anything relevant in the docs, but if iI've missed something, pointers to the relevant doc would be highly appreciated. All the best JM
