[OpenSIPS-Users] Callpickup using EBR

[Bogdan-Andrei Iancu]

Hi Srigo,

So, the calls between FS and Bob/Charlie are 2 different SIP calls, 
right ? and you do EBR on each of them (on the OpenSIPS with usrloc, rigth ?

As I understand from your description, the faulty step is the last one 
when David takes a CANCEL too, right ? Do you have pcaps + debug logs 
for this scenario ?
