[Freeswitch-users] Về: need help on variable and param

13 Apr 2010

      Hi Michael

thank you for your explanation
so the Variables are use for phone call, the params are used for gateway, and sip config file

i found the link that lists of all Variables
http://wiki.freeswitch.org/wiki/Category:Variable

so when i config the gateway/ create new sip profile . 
can i use the variable on the link above to config as a params for gateway/sip profile,  
if not where i can get the list of valid params for gateway + sip configuration

i check the 1000.xml, there is a tag <param> </param>, could you do a brief explain it
<include>
  <user id="1000">
    <params>
      <param name="password" value="$${default_password}"/>
      <param name="vm-password" value="1000"/>
    </params>
    <variables>
      <variable name="toll_allow" value="domestic,international,local"/>
      <variable name="accountcode" value="1000"/>
      <variable name="user_context" value="default"/>
      <variable name="effective_caller_id_name" value="Extension 1000"/>
      <variable name="effective_caller_id_number" value="1000"/>
      <variable name="outbound_caller_id_name" value="$${outbound_caller_name}"/>
      <variable name="outbound_caller_id_number" value="$${outbound_caller_id}"/>
      <variable name="callgroup" value="techsupport"/>
    </variables>
  </user>
</include>

Thank you

Hi all
...
i am confuse the param and variable in freeswitch, sometimes param is used for gateway, sometime variable is used for users
Remember that variables in this case are "channel variables" and are almost always associated with a specific phone call. These variables for a user are set whenever that user makes a phone call.

Parameters a generally used for configuration purposes. The "dial-string" parameter is related to the user channel, so when you do something like:
originate user/1001 &park()

It will use the dial-string parameter to turn "user/1001" into a proper dialstring. If it makes your brain hurt then don't worry about it. :)

Parameters are used in lots of configurations. The most obvious examples are in the SIP profiles and gateways. Are you working on something specific where the differences between params and variables are causing you trouble?
