I am trying to use FreeSWITCH as a SIP proxy.  I have the dialplan below which simply sets bypass_media to true and then bridges to another FreeSWITCH server.

However, when during the call I shut down the proxy FS, the call is immediately dropped.  Why is that?  Is there a way to keep it going?  I understand that in this case I won't be able to properly send the BYE signal when one of the parties hangs up and that's OK.

I tried using redirect and deflect instead of the bridge but those don't seem to work at all - probably because my UAs don't know how to handle redirects.
