Call forwarding - voip

Question

Okay so the problem here is I've been trying to find a dialplan for call forwarding but so far I've found only one on the official site, I configured it according to my requirement but it doesn't work, the call forward number is set but, the call doesn't get forwarded. Could you take a look at the code and tell me what's wrong?
Made some addition in default.xml in the dialplan folder as follows:
<extension name="call_forwarding_activativation">
 <condition field="destination_number" expression="^\*72$">
    <action application="play_and_get_digits" data="3 12 1 14000 # tone_stream://%(10000,0,350,440) silence_stream://250 cfwd_num \d+"/>     
    <action application="hash" data="insert/${domain_name}-call_forward/${caller_id_number}/${cfwd_num}"/>
    <action application="playback" data="tone_stream://${bong-ring}"/>
    <action application="hangup"/>
 </condition>
</extension>
  
<extension name="call_forwarding_deactivation">
 <condition field="destination_number" expression="^\*73$">       
    <action application="hash" data="delete/${domain_name}-call_forward/${caller_id_number}/${destination_number}"/>
    <action application="playback" data="tone_stream://${bong-ring}"/>
    <action application="hangup"/>
 </condition>
</extension>
  
<extension name="call_forwarding_number" continue="true">
 <condition>
    <action application="set" data="call_forwarding_number=${hash(select/${domain_name}-call_forward/${destination_number})}"/>
 </condition>
</extension>
And then added this part of the code to features.xml
<extension name="call_forwarding_activativation">
 <condition field="destination_number" expression="^\*72$">
    <action application="play_and_get_digits" data="3 12 1 14000 # tone_stream://%(10000,0,350,440) silence_stream://250 cfwd_num \d+"/>     
    <action application="hash" data="insert/${domain_name}-call_forward/${caller_id_number}/${cfwd_num}"/>
    <action application="playback" data="tone_stream://${bong-ring}"/>
    <action application="hangup"/>
 </condition>
</extension>
  
<extension name="call_forwarding_deactivation">
 <condition field="destination_number" expression="^\*73$">       
    <action application="hash" data="delete/${domain_name}-call_forward/${caller_id_number}/${destination_number}"/>
    <action application="playback" data="tone_stream://${bong-ring}"/>
    <action application="hangup"/>
 </condition>
</extension>
  
<extension name="call_forwarding_number" continue="true">
 <condition>
    <action application="set" data="call_forwarding_number=${hash(select/${domain_name}-call_forward/${destination_number})}"/>
 </condition>
</extension>
<extension name="check_call_forwarding" condition="true">
<!-- change the following regular expression to match the numbers that will utilize call forwarding-->
 <condition field="destination_number" expression="^(\d+)$">
  <action application="execute_extension" data="is_forward XML features"/>
  <action application="bridge" data="sofia/internal/$1#{domain_name}"/>
 </condition>
</extension>
I tried the code above to implement call forwarding, the forwarding number gets assigned but the call doesn't forward
