Hi, I am using PJSIP 1.14.2 and iOS version 6.1.2. When i am making multiple back to back calls frequently then iOS application get crashed. Crash logs are indicating that crash is occurred in "timer.c". I am attaching snapshot of some crash logs. It will be great if anyone able to point out why this crashes occurring.
