How do I estimate my EnableX platform usage?

The EnableX Video minutes are priced on a per participant/per minute basis. The below working shows how it works.

# of Participants: 2

Duration of call: 30

Total Billable Minutes: = 2 X 30 = 60 minutes

Rate: US$ 0.0045

Total cost of the call will be 60 * 0.0045 = US$ 0.27

How much does recording cost?

There are two components for recordings cost: individual streams and composite transcoded file which combines all participants. Individual stream recording costs $0.01 per minute per stream. The composite file cost is the total duration of the video call at $0.01 per minute. For example, a 5 party 30-minute video call will cost 5*30*0.01=$1.50 for recording plus 0.01*30=$0.3 for transcoding giving a total of $1.8

Does EnableX bill per minute or per seconds?

EnableX bills per minute of connection time for each user i.e. from the point when a user successfully connects to a room until the user is disconnects or gets disconnected.

What are the available pricing plans?

What are payment modes available? Credit card, Debit card. For other forms of payment modes kindly contact sales@enablex.io


What kind of security features does EnableX implement?

EnableX platform is designed with security and privacy in mind.

  • Signaling Encryption: HTTPS with PKI certificate validation
  • All control plane messaging uses HTTPS
  • Media Encryption: AES 256-bit encryption DTLS-SRTP for Audio, Video & Shared Content
  • Infrastructure resides within its own private network and there is no access of the core infrastructure from the public internet. 
  • Every request that is processed by the server needs a valid token authenticated by the system through APP_ID/APP_KEY.
Data & Privacy   All users’ data, including identities, and payment information, stay anonymous. Infrastructure Security   Fortified network with Private VPN accessible only via secure API gateway Secure Protocol   HTTPS authentication and secure RTP for media transportation 
GDPR and HIPPA   EnableX platform is GDPR compliant and HIPPA ready, which means that any business can trust EnableX with data privacy and confidentiality. Encryption   AES256 encryption for all voice, video and signalling traffic PKI Certificate   Valid PKI certs for all customer facing servers

Video is encrypted at the sender endpoint. Once arriving to the media server, each participant’s video is briefly decrypted in memory before immediately being re-encrypted and sent out to other participants. WebRTC requires this, as it does not allow the negotiation of a single set of DTLS keys between more than two participants.

Decrypted video is not stored in any server or storage device or transported over any network. Each participant in an EnableX video room negotiates its own DTLS/SRTP connection to EnableX’s media server and all video streams are subscribed to via secure transport layer.

Does EnableX store customer account information on the EnableX server?

EnableX stores the contact information of its own customers only and not of the end users of your applications/solutions. The information so stored is for billing purposes and to identify each unique customer account and provide safe and secure API keys.

Does EnableX store end user information or end user customer content on EnableX server?

EnableX does not collect and store any end user information from the video and voice chat services made available via the customer API keys of the registered account. The end user information management storage is the responsibility of the Application developer/solution provider.

How do I start recording?

Join the room with a token as a moderator role as below or ensure participants can be assigned moderator role during the session

POST https://api.enablex.io/v1/rooms//tokens
Authorization: Basic XXXXXXX
Content-Type: application/json
“name”: “User Name”,
“role”: “moderator”,
“user_ref”: “XXX”
//To start Recording for a room
room.startRecord (function(result, error ) {
if (result == 0) {
// Recording started

If recording is started, you may check the developer console for the following

{eventType: “roomRecordingSuccess”, roomId: “”, logId: “YyNT2w”, timestamp: Thu Apr 30 2020 21:17:08 GMT-0700 (Pacific Daylight Time), externalIp: “”}
eventType: “roomRecordingSuccess”
externalIp: “”
logId: “YyNT2w”
roomId: “”
timestamp: Thu Apr 30 2020 21:17:08 GMT-0700 (Pacific Daylight Time) {}
// To stop recording for a room room.stopRecord( function(result, error ) {      if (result == 0){          // Recording stopped      }  });

If recording stopped, you may check the developer console for the following

// To stop recording for a room
room.stopRecord( function(result, error ) {
if (result == 0){
// Recording stopped
{eventType: “roomRecordingStopped”, roomId: “”, logId: “YyNT2w”, timestamp: Thu Apr 30 2020 21:18:58 GMT-0700 (Pacific Daylight Time), externalIp: “xxx.xxx.xxx.xxx”}

externalIp: “”
logId: “YyNT2w”
roomId: “”
timestamp: Thu Apr 30 2020 21:18:58 GMT-0700 (Pacific Daylight Time) {}

What is the recording quality and file sizes generated from a recording session?

If room video quality is set to 720p then individual streams will be recorded at 720p while transcoded stream will be 480p

  1. Individual Stream Recording Quality is also set HD 720p max. (Note: 1-to-1 call may continue to have HD streaming throughout the session subject. Network conditions may affect stream quality received at server for recording even if the bitrate is high. In addition, video quality for large party calls may be reduced.
  2. Individual Stream Recording File Size:
    • HD 600MB (Approx.)/Hour (Max size).
    • HD 10MB (Approx.)/ Minute
    • SD 300MB (Approx.)/Hour (Max size).
    • SD 5MB (Approx.)/ Minute
  3. Transcoded File Quality: HD 480p max
  4. Transcoded File Size:
    • SD 300MB (Approx.)/Hour (Max size).
    • SD 5MB (Approx.)/ Minute

How do I fetch recording?

Recordings of your video sessions can be downloaded from your dashboard in portal.enablex.io. Go to Downloads->Recordings and it will show files available for download. Note that your room sessions must end before the individual recorded files and transcoded files can be processed. Also note that processing time would not be immediate. See below how to get notification when recorded files are ready.

Individual Archive

Transcoded archive merges all the individual video sessions into single MP4 file

Retrieve recordings via API is the easiest and most secure. Refer to https://developer.enablex.io/latest/server-api/archive-route/ to set the from and to date to list the recordings

curl -X GET \   -H "Authorization: Basic $(echo -ne   "<APP_ID>:<APP_KEY> " | base64 --wrap 0)"   https://api.enablex.io/v1/archive/period/2020-04-30/2020-05-01   
  "result": "0",
  "archive": [
      "_id": "XXXXX",
      "trans_date": " YYYY-MM-DDTHH:II:SS.mmm ",
      "conf_num": "XXXX",
      "metadata": "PATH_TO.metadata.json",
      "transcoded": [
          "url": "PATH_TO.record.MP4"
      "app_id": "xyz",
      "room_id": "abc",
      "recording": [
          "url": "PATH_TO.record_1.mkv"
          "url": "PATH_TO.record_1.mkv"

To download do the following

curl -o my-transcoded-mp4.mp4 PATH_TO.record.MP4

Delivery of recordings via SFTP and SCP

You may also to get your recording delivered to you via SFTP or SCP. You can do this by login to your portal->Manage Application->Recording Delivery. Only the transcoded file will be delivered per recording. Please test the settings and credentials you entered to ensure we have connectivity to your server.

When can I expect the recording of the session to be delivered to me? Why is there a delay in getting recording?

As soon as your session completes and if the recording was enabled for your session, EnableX platform initiates a transcoding job to mix all participants stream into a composite “mp4” file. The transcoding job is compute intensive and depending on your session duration/number of participants it can take some time to have the recording file of your session available. As soon as the transcoding is complete you will be notified to download your recorded session files (assuming you have setup the notification URL in the portal -> settings)

How do I setup my notification URL as soon as my recordings are available for download after the session?

EnableX may notify you as soon as any recording file is available for downloading by HTTP POST to a designated Notification URL. Go to your Portal Login > My Applications (Left Bar) > Action (Column of Each Row) > Manage Application. See below screenshot

On the Manage Application page, enter the notification URL so that EnableX may perform a HTTP POST to the URL once the recordings are available. EnableX performs a HTTP POST with JSON Raw Body to the URL.

Can any participant start & stop a recording?

No, only a participant with a moderator role can do so. You may assign any participants to have the moderator role during the call session. https://developer.enablex.io/latest/client-api/web-toolkit/moderator-controls/#change-role

Is there an API I can use to fetch usage?  How do I get session usage data? Where can I download usage information?

You may get the session usage of your room via rest API below or you may go to your portal dashboard and download the summary of your session CDR. You will find more information in the developer documentation reference API https://developer.enablex.io/latest/server-api/cdr-route/

Example to obtain CDR for a specified room you may use this below

curl -X GET -H “Authorization: Basic $(echo -ne “<APP_ID>:<APP_KEY>” | base64 –wrap 0)” “https://api.enablex.io/v1/cdr/room/<room_id>” | jq

Is there an API I can use to fetch usage from a start to an end date?

curl -X GET -H “Authorization: Basic $(echo -ne “<APP_ID>:<APP_KEY>” | base64 –wrap 0)” “https://api.enablex.io/v1/cdr/period/2020-04-28/2020-04-30” | jq

You may also fetch CDR for

  • Requesting CDR for a Room & Period
  • Requesting CDR for a Conference Number

Quality Issues


During the session, I keep getting frequent disconnects and reconnects into the room. What should I do?

EnableX, by default, reconnects into the room when   is available. Reconnect is enabled by default into the EnableX room. Room “reconnect” is an optional feature so if you would prefer not to allow the clients to reconnect in case of a network disruption you can switch it off in your client-side application side

How to avoid lip-sync issues?

Have cam/mic from same source/device. This avoids any kind of audio video sync issue.

Participants are constantly getting low bandwidth alert. What is going on?

I am getting “X” error code when I run my code. What does it mean – THIS SECTION CAN CROSS LINK TO ERROR CODES PAGE

Can I see or get error logs? – We can explain about how to see WebRTC internals on the browser here

When I start the session, I get an error saying “ Permission Denied”? What is wrong?

My calls are getting disconnected again and again. What could be the reason?


Do you provide message broadcasting? Yes. More details will be available shortly. Kindly contact sales@enablex.io

Does EnableX provide SIP trunking?
