Istruzioni per la configurazione dei dispositivi VoIP FreeSwitch

Esempio di configurazione di Freeswitch per la connessione a Zadarma.

Dati indicati nell'esempio:

• 111111: Il tuo numero SIP dall'area personale.
• Password: Password: La tua password dal numero SIP, dalla sezione "Impostazioni-Connessione SIP" dall'area personale.
• 1234-100: Il tuo numero interno del centralino dall'area personale.
• Password: La tua password dal numero interno del centralino, dalla sezione "Il mio centralino - Numeri interni" dall'area personale.
• 1000: Numero interno Freeswitch a cui si collega il softphone/telefono IP per ricevere chiamate in entrata ed effettuare chiamate in uscita.

1. Creiamo un file /etc/freeswitch/sip_profiles/external/zadarma.xml

<include>
    <gateway name="zadarma">
        <param name="username" value="111111"/>
        <param name="password" value="Password"/>
        <param name="realm" value="sip.zadarma.com"/>
        <param name="from-user" value="111111"/>
        <param name="from-domain" value="sip.zadarma.com"/>
        <param name="proxy" value="sip.zadarma.com"/>
        <param name="expire-seconds" value="300"/>
        <param name="register" value="true"/>
        <param name="register-transport" value="udp"/>
        <param name="context" value="zadarma"/>
    </gateway>
</include>


<include>
    <gateway name="zadarma">
        <param name="username" value="1234-100"/>
        <param name="password" value="Password"/>
        <param name="realm" value="pbx.zadarma.com"/>
        <param name="from-user" value="1234-100"/>
        <param name="from-domain" value="pbx.zadarma.com"/>
        <param name="proxy" value="pbx.zadarma.com"/>
        <param name="expire-seconds" value="300"/>
        <param name="register" value="true"/>
        <param name="register-transport" value="udp"/>
        <param name="context" value="zadarma"/>
    </gateway>
</include>

2. Creiamo il file con le impostazioni del diaplan /etc/freeswitch/dialplan/zadarma.xml

<?xml version="1.0" encoding="UTF-8"?>
<include>
    <context name="zadarma">
        <extension name="unloop">
            <condition field="$${unroll_loops}" expression="^true$" />
            <condition field="${sip_looped_call}" expression="^true$">
                <action application="deflect" data="${destination_number}" />
            </condition>
        </extension>
        <extension name="in-zadarma">
            <condition field="destination_number" expression="^(111111)$">
                <action application="bridge" data="user/1000@$${domain}"/>
                <action application="hangup"/>
            </condition>
        </extension>
        <extension name="out-zadarma">
            <condition field="destination_number" expression="^(\d{10,15})$">
                <action application="bridge" data="sofia/gateway/zadarma/$1"/>
                <action application="hangup"/>
            </condition>
        </extension>
        <extension name="local">
            <condition field="destination_number" expression="^\d{4}$">
                <action application="answer" />
                <action application="sleep" data="1000" />
                <action application="bridge" data="user/${destination_number}@$${domain}" />
                <action application="hangup" />
            </condition>
        </extension>
    </context>
</include>



<?xml version="1.0" encoding="UTF-8"?>
<include>
    <context name="zadarma">
        <extension name="unloop">
            <condition field="$${unroll_loops}" expression="^true$" />
            <condition field="${sip_looped_call}" expression="^true$">
                <action application="deflect" data="${destination_number}" />
            </condition>
        </extension>
        <extension name="in-zadarma">
            <condition field="destination_number" expression="^(1234-100)$">
                <action application="bridge" data="user/1000@$${domain}"/>
                <action application="hangup"/>
            </condition>
        </extension>
        <extension name="out-zadarma">
            <condition field="destination_number" expression="^(\d{10,15})$">
                <action application="bridge" data="sofia/gateway/zadarma/$1"/>
                <action application="hangup"/>
            </condition>
        </extension>
        <extension name="local">
            <condition field="destination_number" expression="^\d{4}$">
                <action application="answer" />
                <action application="sleep" data="1000" />
                <action application="bridge" data="user/${destination_number}@$${domain}" />
                <action application="hangup" />
            </condition>
        </extension>
    </context>
</include>

3. Creiamo in Freeswitch il numero interno 1000 al quale si collegherà il softphone/telefono IP per ricevere chiamate in entrata ed effettuare chiamate in uscita. Modifichiamo il file /etc/freeswitch/directory/default/1000.xml

‎‎

<include>
    <user id="1000">
        <params>
            <param name="password" value="your_hard_pasword"/>
            <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="zadarma"/>
            <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>

Affinché Freeswitch rileggi i file di configurazione, è necessario eseguire il comando fs_cli -x reloadxml.fs_cli -x reloadxml

Configurazione di Freeswitch completata.
