Webhooks are not fired. API nexmo

Question

I use the nexmo api to redirect all call to a virtual us number to a real number.

To implement i use this request : https://developer.nexmo.com/api/developer/numbers#update-a-number

With params below:

1. moHttpUrl : an url (https) on my server which respond 200 OK
2. country : US
3. misdn : the us virtual number
4. voiceCallbackType : tel
5. voiceCallbackValue : the real forward
6. voiceStatusCallback : an url (https) on my server which respond 200 OK

(The data is well recorded, i can see it on nexmo backoffice)

Problem : when i call the us number with my phone, the redirection is ok. I stay on line 10 seconds and stop the call.

At the moment nexmo should call my voiceStatusCallback but do nothing. Furthermore i have no idea on which informations are passing with the webhook.

Thx for your help.

It looks like your problem is related to https, the simple call forwarding is part of our deprecated voice API and as such that only supports SHA-1 certs on https, so I'm imagining this is your problem. https://help.nexmo.com/hc/en-us/articles/115005461928

There are 2 options, either use http for your callback (not great I know) or take a look at our new Voice API which will give you a lot more control, if you want to do a simple call forward you would just need to host a JSON file on a URL somewhere that contains a connect action see https://developer.nexmo.com/api/voice/ncco#connect You will then get a whole bunch of call event webhooks such as when the call starts, is answered and ends.
