"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

Audio and Video record`s URL length can be more than 255 characters.

For the last 5 years, we have been keeping record`s URL length short. To make our platform better we are now removing the limit, so URL length can be longer than 255 characters. The change is important to our clients who use MySQL 'varchar' type for record`s URL storage. Please ensure that you don't have any '255' characters limits in your code while working with URLs received from Voximplant API!

Hot Summer Speech-to-Text Updates


Following Google’s release of new Speech API, we are happy to announce improved quality of call records transcription. No changes are required, your old code like

call.record({ transcribe: true, language: ASRLanguage.ENGLISH_US })

Blind transfer support for SIP phones

A lot of traditional telephony services rely on this function. It lets callee transfer a call to another person by pressing special transfer button and entering another person's number (usually extension number). It's called blind transfer because the person who transfers the call won't talk with the person to whom he transfers it.

Blind transfer The following scheme describes the process in Voximplant terms:

Diff in VoxEngine scenarios editor

Many voximplant developers use our online VoxEngine scenarios editor. It simplifies the development process since it has autocomplete and other useful functions, but there was a problem some our developers reported about - it's hard to check the changes in the scenario before you save it, so the wrong version of the scenario can be saved accidentally. We have embedded the Diff utility that shows the difference between a scenario version which is now stored in the voximplant's cloud and the one with the recent changes that will be saved. Developers can find the Diff button and Enforce Diff checkbox near the Save button now.

Diff
If the Enforce Diff checkbox is active then Diff util will be launched before scenario can be saved.

VoxImplant Instant Messaging

IMVoxImplant helps app developers build better real-time communication apps faster and for our teamc v real-time communication includes number of different things. We've stared with audio, then we've added video calls and now it's time to let our developers use instant messaging and presence - two very important features of UC stack. We also ready to take care of rosters/contact lists - VoxImplant developers can now integrate full featured messenger functionality into their apps in minutes. When we've been working on this update we tried to imagine different services our developers could build using this capabilities (for b2b and b2c), so in addition to personal roster (every app user can create it by himself like in Skype and other messengers) we created application roster - it includes all app users and can be rather useful for b2b apps (something similar to Slack or Lync). In 2017 we updated our messanger API, so please check this link for details and how-to's!
