Call status

[ip19]

Hi,
I am writing a VAD project for a support center that in the night time want to divert the support calls to the user only if the custumer is recognised and have a valid contract.
All the VAD project works fine, from the Caller ID or from a PIN i can recognize the custumer and evaluate if it have a valid contract or not and if it's ok it transfer the call to the cellular phone of the night reperible user.

The problem is that I can't have a controll of the tranfered call, so I dont't know if the call is correctly sent to the night operator or if it was non reperible for example becouse the cellular phone was powered down.. after the call transfer is made, the VAD goes anytime to DISCONNECT HANDLER FLOW and i can't decide for exaple to trasfer to a second emergency number if the first call transfer was not good.

Do you have any ideas?

thanks

Hi,

From the VAD using standard components you can only make a blind transfer, so you don't have any feedback about the transfer result.

If you really need to be sure that the call is transferred, the only option I see is creating a DLL and use the following API inside:
http://www.3cx.com/blog/docs/call-control-api/

Your new DLL could be triggered from the VAD with an External Code Execution component, and from there you can take control of the call. You will need to pass the callid to the DLL, so it knows which call to transfer.

The API is not very well documented and it requires some advanced programming knowledge.

Hope the information helps.

Regards,

I just made a post about this, so I'm repeating myself. But the problem here is that the CAll ID which the VAD uses is not the same one that you get in the Call Control API.

Hi,
I'm tryng to log the call time before the transfer and after the line release into the db to have an indication if the call was correctly divert to the cell phone (>30 sec) or not (<30sec) and then try to launch a call or an email warning to the second technical guy

I will update you
