SOLVED Obihai Obi110 as a FXO device

[trumee]

Hello,

I have an Obihai Obi110 device which is connected to a landline. I want to use it as an FXO device with Freeswitch/Fusionpbx. I have setup the SP1 Service and have specified 'li' in X_InboundCallRoute. In Fusionpbx my dial plan is as follows:

<extension name="transfer.International" continue="false" uuid="6d1673d9-bc23-4a2f-8da7-fa82c578b566">
    <condition field="${user_exists}" expression="false"/>
    <condition field="destination_number" expression="^(\+1|001)(\d{10,20})$">
        <action application="export" data="call_direction=outbound"/>
        <action application="set" data="effective_caller_id_name=${outbound_caller_id_name}"/>
        <action application="set" data="hangup_after_bridge=true"/>
        <action application="unset" data="call_timeout"/>
        <action application="set" data="continue_on_fail=true"/>
        <action application="bridge" data="sofia/internal/$1@172.16.2.3"/>
    </condition>
</extension>

The Obihai device is at 172.16.2.3. Unfortunately, my OBI device simply reboots when i try to make a call. Any idea what could be the issue?

This is for FreePBX but the concept is same; have a close look at the X_AccessList on the page: https://wiki.freepbx.org/pages/viewpage.action?pageId=4161594

and the FreeSWITCH wiki: https://freeswitch.org/confluence/display/FREESWITCH/Obihai

Thanks, I looked at the Freeswitch page. Any idea what the following means:

<action application="bridge" data="{originate_timeout=25},${group_call(bria@${domain_name}+A)},${group_call(deskphone@${domain_name}+A)}"/>

I tried calling from the phone connected to the FXS port of the Obihai, and it was able to route calls correctly through the FXO (PSTN) port.

Any idea what the following means:

Ignore that and use a normal bridge with gw configured for obi

I changed the dial string to {absolute_codec_string=PCMU}sofia/internal/$3@172.16.2.3 and it worked. The dial plan which works is as follows:

<extension name="transfer.International" continue="false" uuid="6d1673d9-bc23-4a2f-8da7-fa82c578b566">
    <condition field="${user_exists}" expression="false"/>
    <condition field="destination_number" expression="^(\+|00)(1)(\d{10,20})$">
        <action application="export" data="call_direction=outbound"/>
        <action application="set" data="effective_caller_id_name=Landline"/>
        <action application="set" data="effective_caller_id_number=11111"/>
        <action application="set" data="callee_id_number=$1"/>
        <action application="set" data="hangup_after_bridge=false"/>
        <action application="set" data="ignore_early_media=true"/>
        <action application="unset" data="call_timeout"/>
        <action application="set" data="continue_on_fail=true"/>
        <action application="bridge" data="{absolute_codec_string=PCMU}sofia/internal/$3@172.16.2.3"/>
    </condition>
</extension>

Interesting, do you have multiple codecs enabled on the Obi?

HAve you tried this behind NAT? I successfully registered OBI110 FXO behind NAT and set it up as a gateway but cant place or receive calls.
