[Freeswitch-dev] Bridge dialplan to sipx IVR services problem

[Joegen E. Baclor]

Hi Anthony sorry for being vague.  The call flow i am experimenting on 
looks like this

1.  UA1 ->  sipXproxy -> [FS (bridged-dial-plan)] -> [FS 
(auto-attendant-socket dial-plan)]
2.  [FS (auto-attendant-socket dial-plan]) sends REFER to [FS 
(bridged-dial-plan)]
3.  B-Leg of [FS (bridged-dial-plan)] consumes REFER and sends INVITE 
to  Refer-to URI via sipXproxy

The way sipX does this right now is REFER is actually processed by UA1.  
Having [FS (bridged-dial-plan)] breaks this.

I have reason to believe that the ultimate answer to my previous 
question would be a no.  Replicating authentication credentials would be 
costly as well as create a security hole since any UA which has a valid 
extension in the from URI can now make calls through the AA without 
being challenged since FS assumes authentication.

I am thinking that we could still make the old behavior a possibility if 
there is a way to intsruct A Leg of the bridge call perform the REFER 
instead of the auto-attendant leg sending it.  Is this possible?

Thanks for you patience.

Joegen
