Seems no any response from far side... Do you have any ideas??



Only one time, I got the following log:


#./testcall

Chan 2, class 'mfcr2', variant 'ar,20,4', end 2, caller 0, from '' to ''

MFC/R2 Chan   2: Unblock

But after rerunning the test, I only get the first log (w/o Far end
replies.)



Any help will be really appreciated!



Thank you!

That means someone else has already open the zap device, most likely
Asterisk. Just one application at a given time can open a zap device.
You cannot run testcall and Asterisk at the same time unless you make
sure they don't try to open the same channels.
