[Freeswitch-docs] call forwarding

[Nicholas Schoonover]

I added some documentation around the  logic that forwards calls to the 
'is_forward' extension. I am new to Freeswitch and was stuck on how to 
set up call forwarding for a bit. I thought some more instruction around 
this area would help people who are new to the concepts in Freeswitch. 
Is this change logical?

In my personal set up I put this application,

      <action application="set" 
data="call_forwarding_number=${hash(select/${domain_name}-call_forward/${destination_number})}"/>

into the 'check_call_forwarding' extension and got rid of the 
'call_forwarding_number' extension. This made sense to me because it 
sets 'call_forwarding_number' in the extension before 'is_forward' 
rather than at the end of the dialplan. Am I misunderstanding something? 
Would this be a more logical way to format the documentation?

I used this as my check call forwarding extension and did away with the 
'call_forwarding_number' extension at the bottom.

<extension name="check_call_forwarding" continue="true">
<condition field="destination_number" expression="^(\d+)$">
<action application="set" 
data="call_forwarding_number=${hash(select/${domain_name}-call_forward/${destination_number})}"/>
<action application="execute_extension" data="is_forward XML features"/>
<action application="bridge" data="sofia/internal/$1@${domain_name}"/>
</condition>
</extension>

Sorry if I am being unclear or am misunderstanding something.

Thanks,
