来自网络的Android来电阻止

I made a service to monitor all the incoming and outgoing calls of android device on my website but now I want to block the calls from specific number from the same webpage.

Is their is anyway to do call blocking on android device by php or javascript code?

In the telephony broadcast receive, check if the number is one of the blocked number? If condition is satisfied then use following code to end it:

telephonyService.endCall();
