"callPSTN" now requires a caller id

For the last five years, it has been possible to initiate outgoing calls via Voximplant cloud without specifying a source phone number. Such feature was provided mainly for new developers, and if an optional caller id was not specified, the special “fallback” number was used automatically. However, the telecom landscape has changed so far, and now many telecom operators drop such calls, which results in unwanted side-effects for the “call without a caller id” feature.

Starting on April 25 we change our callPSTN API: “caller id” is no longer optional and must be specified in your JavaScript source code for scenarios. You can use following phone numbers as a callPSTN caller id:

  • Phone numbers rented from Voximplant;
  • Phone numbers confirmed via the Voximplant control panel;
  • Incoming call phone number, if a JavaScript session has an incoming call;

Our developers can answer all your questions via support@voximplant.com

Voximplant Kit vs Talkdesk: Comparing contact centers for the small and medium enterprise

Any contact center manager considering a new cloud communications solution needs to do their “due diligence” before choosing a provider, including those in small to medium enterprises.

Your decision not only affects your organization’s budget, but also its business processes, customer experiences, and agent work environment.

What is a No-code Contact Center?

If you’re involved in evaluating cloud contact center services, you’ve likely recognized two distinct categories and a big difference in the amount of technical expertise required to implement them. You’re attracted to the ease of use offered by contact center as service (CCaaS) offerings, but their fixed functionality doesn’t fit your business needs. In contrast, a cloud contact center built on a communications platform as a service (CPaaS) offering provides unlimited flexibility, but requires expensive software development resources to build a complete solution.
