I have the following issue: if I do a bridge of an inbound call to an outbound call, when the called number answer the call with a 200 OK, FreeSwitch sends the ACK instantely, without wait the ACK of the calling.

The message flow (as shown in the attached .png) is:

CALLING              FS       CALLED

INVITE       --------->

100 Trying <---------

                             -------------> INVITE

                             <--------- 100 Trying 

                             <--------- 200 OK

                             -------------> ACK

<--------- 200 OK

-------------> ACK

When I expected that the ACK to called is related to ACK from the calling:

CALLING              FS       CALLED

INVITE       --------->

100 Trying <---------

                             -------------> INVITE

                             <--------- 100 Trying 

                             <--------- 200 OK

<--------- 200 OK

-------------> ACK

                             -------------> ACK

For this reason, if sometimes the Calling doesn't send the ACK (because it reject the 200 OK), the call is considered connected (and billed) by Freeswitch (30s, probably due to a timeout waiting ack) and not by Calling (0s).

There is a way (config?) to send ACK to called only when is received the ACK from calling?
