hello,

I can receive and send a fax in php already.

Now, I want to set a specific fxo port, not the whole gateway, to send a fax. 

What configuration should I set? 

The environment is described as follow:

a freeswitch server based on winxp. 
server ip: 192.168.1.1

a WellGate 2644 gateway which has 4 fxo and 4 fxs. each fxs/fxo port can register an sip account to freeswitch
gateway ip: 192.168.1.2

i config my gateway as below in freeswitch:
    <gateways>
      <gateway name="faxgw">
<param name="username" value="0000"/>
<param name="password" value="0000"/>
<param name="realm" value="192.168.1.2"/>
        <param name="register" value="false"/>
      </gateway>
    </gateways>
 

the gateway register 2 user as below
  <user id="pstn_fxo1">
    <params>
      <param name="password" value="1234" />
    </params>
    <variables>
      <variable name="user_context" value="default"/>
      <variable name="toll_allow" value="domestic,international,local" />
      <variable name="effective_caller_id_name" value="pstn_fxo1" />
    </variables>
  </user>

  <user id="pstn_fxo2">
    <params>
      <param name="password" value="1234" />
    </params>
    <variables>
      <variable name="user_context" value="default"/>
      <variable name="toll_allow" value="domestic,international,local" />
      <variable name="effective_caller_id_name" value="pstn_fxo2" />
    </variables>
  </user>


in my php file, i can send the fax via fxo1 pstn line (use event_socket_request) and the command is 
"api originate sofia/gateway/faxgw/". $dest_phone_number. " &txfax(tmp.tif)"

my problem is
1. How to send fax via fxo2 pstn line
    Should i bridge to user "pstn_fxo2" first and then dial number?
    I try to use
    "api originate sofia/internal/pstn_fxo2 ".$dest_phone_number. " &txfax(tmp.tif)"
    but it didnt work

2. In <gateway> config
    The "username" and "password" seem no effect. I just set the "realm" to my gateway ip and it works.
    And the "register" i dont know it too.
    The document didnt describe it clearly, can u explain it for me

Thank you sincerely.

Joy
