is it possible for Asterisk to open a specific web page when a call comes in relating to that call?
EG if ABC Company calls, then Asterisk opens a web page specfic to ABC company?
Any help would be much appreciated.
Assuming the web page isn't for the phone, you would write an AMI application that monitored events and did this.
I my case I have completed such task in the following way a php script running on background , monitoring ManagerEvent Newchannel, once the event is triggered I fired a postback request using curl to an external webservice, with the variables avaiables on the caught event
