Add Flowroute as a SIP Gateway to FreeSWITCH

This article provides a basic starting configuration to get FreeSWITCH up-and-running with Flowroute as the external SIP. This article was written using a 64-bit Debian 3.16.7 Linux system with a static public IP running FreeSWITCH Version 1.6.2. See the Freeswitch Installation Guide for more info on installing FreeSWITCH.

NOTE: This guide requires Flowroute's recommended firewall rules be configured to allow Flowroute related traffic onto your network.

Before you begin

Have your Flowroute SIP Credentials (Tech Prefix/Username & Auth Username, and Password), found on the Interconnection > Registration page of Flowroute Manage.

To configure FreeSWITCH with Flowroute:

Install FreeSWITCH and any required dependencies.
Create the directory /etc/freeswitch/sip_profiles/external/

Paste the following XML code into flowroute.xml, replacing TECH_PREFIX and PASSWORD with your Flowroute SIP Credentials information found on the Interconnection page of Flowroute Manage.

<include/>
    <gateway name="flowroute">
      <!-- Replace TECH_PREFIX with SIP credential username -->
      <param name="username" value="TECH_PREFIX"/>
      <param name="auth-username" value="TECH_PREFIX"/>
      <!-- Replace SIP_PASSWORD with SIP credential password -->
      <param name="password" value="SIP_PASSWORD"/>
      <param name="proxy" value="preferred PoP.sip.flowroute.com"/>
      <param name="expire-seconds" value="600"/>
      <!-- Switch to "false" to disable SIP Registration --> 
      <param name="register" value="true"/>
      <param name="retry-seconds" value="30"/>
      <param name="dtmf-type" value="rfc2833"/>
    </gateway>
</include>

After saving the file, run the following:

fs_cli -x "sofia profile restart all";

Congratulations! You now have a Flowroute SIP gateway configured in FreeSWITCH
