Hi Guys, What's the default for VAD in the sip profiles if none is specified? I get choppy audio without explicity setting it to none, is there anything I can check/try to improve the situation? Hardware wise it's a rackspace cloud server (but it does have a 1000Hz preemptible kernel, and otherwise seems fine) but I'll be testing again on a proper machine in the coming days and network wise it's over the internet (just in case latency causes issues with VAD). It's not a massive issue in reality, just that rackspace charge for traffic, so thought it might be worth trying to cut it down. -- *Andrew Cassidy BSc (Hons) MBCS SSCA* Managing Director *T <info@cassidywebservices.co.uk> *03300 100 960 *F<info@cassidywebservices.co.uk> *03300 100 961 *E <info@cassidywebservices.co.uk> *andrew@cassidywebservices.co.uk *W <info@cassidywebservices.co.uk> *www.cassidywebservices.co.uk
