[Linphone-developers] Debugging information

[Michel Ferreira Bueno]

Hello.

We are facing some problems to establish a SIP call originated on our SIP 
Server to our android application in some specific device models. There is no 
response from these target devices for the INVITE message.
For debugging purposes I would like to insert some log messages to help me 
isolate the problem and discover what is happening.
I suspect that the INVITE message is not even arriving at the android 
application and that is why nothing happens there. No debug messages are 
printed on the LogCat when the INVITE message is sent by our SIP Server to one 
of these devices.
So, to start my investigation I would like to know for sure that the android 
application did receive something or did not. If it did receive the message, 
maybe there is some problem with the INVITE message itself.

Any suggestions about where should I start inserting logs?
It would be ideal to know some parts of the code to start looking since I am 
not familiar with the lib code.

Any hint like function names or file names will be very helpful at this moment.

Thanks a lot.
