With pjsip 2.1 on iOS, I experience intermittent echo while using the library through the pjsua API. I have tried using both the hardware Echo Cancellation and the Speex Echo Canceller.Also, I have tried setting the ECTail value to 1000ms instead of the default 128ms.The clock rate is set at 24kHz. Seems to happen on certain devices and not others - for instance, certain iPhone 5s but not others.Has anyone experienced this issue and what would be the recommended solution?
