[Freeswitch-dev] call forward howto

The transfer app sends the same call to some other extension at some other
dialplan within the switch.
We are not a sip specific switch so we have to abstract many concepts.

If you are trying to redirect the call we have 2 ways
the redirect application

<action application="redirect" data="sip:user at host"/>
This will result in a 302 redirect in the case of a sip channel

<action application="deflect" data="sip:user at host"/>
This will result in a REFER to the specified uri

That is the only 2 ways we support, if you are looking to divert like a
proxy does
remember we are only a b2bua and do not perform proxy features, see openser
for that.
