WebHook not receiving calls
Tags: webhooks
Jan 10, 2017 at 11:33am   •   6 replies  •  0 likes

Hi All, I have successfully registered a WebHook for purpose of monitoring incoming calls. I am working against Sandbox environment. I am not receiving any calls on my WebHook.

I saw similar questions but they were resolved with no further explanation.

My webhook is a Java servlet, I utilized ngrok as advised. I am placing a call to sandbox phone number, then I am dialing extension 101, neither events send a call to my web hook. Here is how my subscription list look like:

{ "uri": "";,

"records": [


"uri": ";,

"id": "8418023a-3663-40c1-9a2b-f078d20b2829",

"creationTime": "2017-01-10T18:42:50.856Z",

"status": "Active",

"eventFilters": [









"expirationTime": "2017-01-17T18:42:50.856Z",

"expiresIn": 601984,

"deliveryMode": {

"transportType": "WebHook",

"encryption": false,

"address": "";

Thanks for the update and information, I totally forgot about that requirement. Appreciate you investing time and sharing the results.

Problem solved. Extension must be in use(by a physical or softphone) otherwise webhook events are not sent.

Thank you all!

In your sandbox if you go into the call logs screen and on any row hover your mouse over the column called result a message bubble will appear letting you know if you have any or not. Also, if you call your company number with your mobile phone you should receive a message stating "Voice mail is full".

Kobie, thanks for reply. Where should I see my credits? I couldnt find any reference of 'Sandbox credit'. Also I dont think I have sone anything that could spend any kind of credit so far and I am not placing calls from API, I am trying to call my main companay number, expecting it will trigger a call to my subscribed WebHook

Check to see if you have enough calling credits. You are given 500 credits/month this is if you are not a paying customer in your sandbox account.
