I am developing a SIP application for making and receiving a call. For that purpose I did analysis on open source project SipDroid. in that project how they catch the value of dialpads pressed button which is sent to the particular method for making a SIP call.
I tried to find the code for that task but I didn’t get anything.in which file the code is resides to catch that value in SipDroid project?
The calls in SipDroid are handled by the SipdroidEngine:
The method that handles the initial operation is with signature
public boolean call(String target_url,boolean force)– it transfers the call to the SipDroid UserAgent class and so on, until it reaches the network transport layer. Just check the references of this call method in the whole project and see where it’s used.
