How to Build VoIP Route Testing Tool ?

Daily route testing and CLI verification is a must have task today for every Carrier and VoIP Service provider, there are some great tools that exist today, they do the job well but we think not everyone can afford the high rates and licensing fees that these providers are requesting you to pay for the service.

We believe these high costs can cause operators to avoid testing routes more often as they should and this will lead to a degraded performance in VoIP networks due to this.

Since TelecomsXChange has a great number of carriers already on the platform we decided to give you a simple API that you can utilize to initiate route tests from any Web or Mobile application within a few clicks and get the results and pay per minute the regular termination rate and billing interval as you would normally pay if you would test manually.

You can initially test pre-configured and ready to go 300+ carriers including TATA, IDT, BICS, SpeedFlow, Lexico and many others, incase there is a carrier not on the platform you can also add him privately under your seller account and use the i_connection id parameters to initiate the tests to it.

A finished product will look like this:

The simple script below allows you to:

• Initiate test calls on any carrier on TelecomsXChange including your self via a simple HTTP API call
• CLI verification right on your phone number
• Set Custom caller IDs
• Get charged per minute not per test

<?php

$tcxc_host = "https://members.telecomsxchange.com";

//TCXC Buyer login
$login = "{{ Buyer_Username }}";

// TCXC (TelecomsXChange) API key, Generated from Buyer Portal, Preferences Page:

$api_key = "{{ API_KEY }}";

// TCXC i_account that you want to use for Callback billing, 


$i_account = 1;  // You can get account ID from Accounts Page


//legA parameters

$cld1 = "19542405555";  //First number to dial
$cli1 = "1800999999";  // Caller ID to show first number
$i_connection1 = 315;  // Carrier to use e.g 315 is TATA Communications

//legB parameters
$cld2 = "18667478647"; //Second number to dial
$cli2 = "962790321224"; //Caller ID t show destination number
$i_connection2 = 529;  // Carrier to use e.g 529 is IBASIS

$ts = time();   // Get Current Time Stamp

$check_uri = "/api/callback/initiate/$login/$i_account/$cld1/$cli1/$i_connection1/$cld2/$cli2/$i_connection2/$ts/";

// Signing the API key for better security

$sign = hash('sha256',$check_uri . $api_key);

// initiate the call from your script

$handle=curl_init( $tcxc_host . $check_uri . $sign );

curl_setopt($handle, CURLOPT_VERBOSE, true);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($handle, CURLOPT_SSL_VERIFYHOST, false);

$content = curl_exec($handle);

echo $content;

CLI Verification

To verify the CLI you can do it in different ways:

1- CLD2 (Destination Number) can be a mobile or landline DID number that you point back to your softswitch to see the the CLI delivered by the test call, you simply point the DID number to your SIP server and authorize it.

2- CLD 2 (Destination Number) can be any random number that IVR message asks them to announce what is the caller ID they got, with speech to text api you can convert the said number to text and send it to your web hook.

3- CLD2 (Destination Number) can be your own phone number which you can receive calls on and check caller id.

Code can be annoying sometimes, so please do not hesitate to reach out to support@telecomsxchange.com if you get stuck and our team will help you right away to build your tool.
